He should have put the plants in a place where they would get enough radiant energy (sunlight) to allow them to photosynthesise. Next term in Matter and Materials, we will look at this again and find out about the chemical reaction taking place in the test. What did you learn from doing this investigation? The seven life processes are: movement (moving), reproduction (reproducing), sense the environment (sensing), growth (growing), respiration, excretion (excreting), nutrition (feeding). They are glucose (food) and oxygen. Upgrade to remove ads. Plant cells respire, just as animal cells do. Some objects with potential energy are a book on the table (it has gravitational potential energy as it can fall down to the ground), a bouncing ball when it is at the top of its bounce as it can also fall back down, a batteries, fossil fuels have and food have potential energy. The gas that they collected from each test tube was run through limewater. All living things require energy to survive. Match. For now, let's use this test to show that our breath contains carbon dioxide. This provides them with energy. [2 marks], Predict what would have happened after another few days with the beans hidden in his cupboard. The leaf is then removed and dipped into hot water to soften it as the ethanol will make the leaf brittle. Cell Energy (Photosynthesis and Respiration) Notes I. ... What is a requirement for accurate measurements of the rate of respiration using a respirometer? Unlike photosynthesis, where we place sunlight energy above the arrow and not as one of the reactants in the equation, in respiration, we place energy here as a product. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. Think of possible tests that can be done to determine whether a plant has produced either starch or glucose. Help them by reminding them of the two types of energy, namely kinetic energy and potential energy. As air contains such a small percentage of carbon dioxide, there is not enough to cause a noticeable difference in the limewater. We have now learnt about how plants produce glucose and store it as starch, but how do we know for sure? Like it? The carbon dioxide that is produced in the body of an organism during respiration needs to be removed. An idea as introduction and/or conclusion to this section on Respiration is to let learners watch the YouTube video of a song about cell respiration: bit.ly/1eupZUz. The equations are as follows: Photosynthesis: 6CO 2 + 6 H 2 O + energy -> C 6 H 12 O 6 +6O 2 o Carbon dioxide plus water plus energy yields sugar and oxygen [1 mark], Why do you think the yeast solution in Set-up 1 did not produce carbon dioxide. Learners need to apply what they have learnt in Part 1 to plan their own experiment in part 2 and write up an experimental report. Explain what he would have noticed a few days after planting the beans. Notice what happens to the clear limewater. At the to… 6Co2+6H2O—>C6H12O6+6O2 Where does the energy come from in photosynthesis? Sugar and oxygen O2 are produced in photosynthesis. This being the first investigation that they will perform in high school, this activity will allow teachers to gauge their level of proficiency and abilities in this regard. A concept map gives us a more visual way of summarizing information. The processes of photosynthesis and cellular respiration are linked to each other. Why did the farmer see this result? "Knowledge is real knowledge only when it is acquired by the efforts of your intellect, not by memory." Then the leaf must be placed in alcohol and this is heated over water to remove the chlorophyll. Have a look at the following photos which illustrate this. What are these? Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on earth. ... What happens in both respiration and photosynthesis? … Below is the complete concept map with the answers filled in. Abstract. Photosynthesis & Respiration (Simulations) INTRODUCTION All living organisms have a constant energy requirement, and they have mechanisms to gather, store, and use energy. After this, place the leaf into the beaker with the ethyl alcohol. Have a look at the following photos of different plants. Therefore, to see if a plant photosynthesises, we can test to see if the plant produced starch. ATP is produced. All living organisms need to undergo respiration to release energy from chemical potential energy and perform the seven life processes. This is one skill which might help them later in their school career where they have a lot more information to ingest and learn and make sense of. Plants only photosynthesise during the day, and not at night. Search. It is also important to make sure that the only thing affecting the limewater was the gas released in the experiment, and not carbon dioxide from the atmosphere. As we learnt in Matter and Materials in Gr. Carbohydrates are temporary energy stores. What does this mean? The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. There are two parts to this investigation. Trapper plants were inoculated and grown in a controlled environment on N-free nutrient solution. Concept mapping is one tool for summarising information and understanding how different concepts link together. Point out that air from your lungs contains a much higher percentage of carbon dioxide from respiration and so this is able to turn the limewater cloudy in a shorter time than atmospheric air will. You will need variegated and normal leaves for this investigation. Tags: Question 22 . This activity may be done in groups or individually. This is the metabolic process in all organisms where oxygen is combined with glucose to release water and carbon dioxide and energy in the form of ATP (adenosine triphosphate). The food that a plant produces is used by animals when they eat the plant and by other animals that eat them. STUDY. Cells then use this energy to perform work, such as cellular respiration. Give reasons for your answer. This is what learners' diagrams should look like: Have you noticed the VISIT boxes in the margins which contain links? Chloroplasts are a type of organelle found only in plant cells. Google Classroom Facebook Twitter. This process is called respiration. This food contains chemical potential energy that needs to be released from the food. In your discussion, you need to explain your results and what they mean. Fill in the products of photosynthesis in the block on the right. The word and symbol equations for photosynthesis are: Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. The second method which has been employed is the measurement of oxygen uptake of illuminated cells deprived of C02 (inhibition of photosynthesis) (3). Next term in Matter and Materials, we will look at chemical reactions and define the 'ingredients' as reactants. Energy –ability to do work; forms of energy: heat, light, chemical, electrical, mechanical, kinetic, potential A. Place the leave in a petri dish and cover the leaf with iodine. Practice: Free energy, photosynthesis, and cellular respiration. [2 marks]. The water in the saucepan will distribute the heat evenly to warm the ethyl alcohol evenly. Discuss this with your learners. Click card to see definition true: Energy is released in respiration. Place the leaf into warm water to soften it. This type of respiration occurs in three steps: glycolysis; the Krebs cycle; and electron transport phosphorylation. The plant converts the glucose to starch as it is easier to store. 6, this means that glucose can dissolve in water. Why were some plants placed in a well-lit area with direct sunlight and others in the dark? The plant cannot have large amounts of glucose accumulating as this affects the water potential within the leaves, and so some is converted to starch to be stored until it is needed. Quiz not found! Allow learners the freedom to tabulate their results in any way they choose as long as it is easy to interpret and understand. photosynthesis-and-respiration-concept-mapping-answer-key 2/2 Downloaded from lsamp.coas.howard.edu on January 6, 2021 by guest the gap between educational psychology and classroom management. Summarise what you have learnt about respiration in the summary diagram below. Which test tube do you think it is and from which set-up. This is useful to the plant as it means it can transport the glucose in water to where it is needed elsewhere in the plant. The clear limewater did not change and remained clear. [2 marks], Study the following diagram and fill in the missing information. Therefore, the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117 kcal, divided by 450—that is, 117/450, or 26 percent. 2. We think you are located in After 24 hours, pour 50 ml of the ethyl alcohol into the beaker and place it in the saucepan with water. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. In this chapter we are going to investigate the processes involved in transferring the Sun's energy to our bodies to allow us to read this text! Remove one healthy looking leaf from the pot plants that were in the well-lit area exposed to direct sunlight. Various topics on the subject highlight the history, importance, process and future of photosynthesis. The bean plants would die as the leaves would not have enough radiant energy to allow them to photosynthesise and produce glucose for the plants to use to grow and develop. Energy is required to break down and build up molecules and to transport many molecules across plasma ... Autotrophic organisms perform both photosynthesis and respiration. The need for energy drives the interactions and interdependence in an ecosystem. Record your observations in the table. For example, the temperature of the water will affect the rate at which it dissolves, as will the quantities used, etc. This is the currently selected item. The lower quantum requirement obtained at low light intensity is believed to be due to a relatively greater importance of contribution of energy from respiration to photosynthesis. Leaves are not the only parts of plants that store starch. 1 big yellow energy sign; 2. For example, a reptile can lie in the Sun to warm up from the heat energy, but this does not provide the necessary energy for that animal to move, reproduce or excrete waste. Free energy, photosynthesis, and cellular respiration. Which banana do you think contains the most starch and the least glucose (a sugar) based on the taste test? H 2 O. NADPH. Photosynthesis requires energy in the form of light to drive the chemical reaction. Pisum sativum L. cv. This website has many interesting articles about science and science related jobs. There are many examples of South African plants that have variegated leaves, such as some geraniums, African violets, ivy, etc. It is important that learners be made aware that we do not taste-test unknown substances due to the potential for poisoning. Write. All life on Earth depends on energy to sustain the seven life processes. ATP provides the energy that carried molecules found in living cells required in the process of photosynthesis. Compare And Contrast Photosynthesis And Cellular Respiration By Completing The Table. After 4 weeks N was supplied to treatment plants as NH 4 NO 3, KNO 3, or NH 4 Cl and rates of C 2 H 2 reduction, root + nodule respiration, and leaf photosynthesis were determined 1 week later. Learners should be able to quite easily see this based on the speed with which the iodine changes colour in the unripe banana. Photosynthesis occurs when plants use CO2 and water to produce carbohydrates in the presence of solar power while cellular respiration utilizes the carbohydrates to produce energy. Some leaves may need to be flooded with iodine solution. PLAY. Energy is required for photosynthesis, but energy is released during cellular respiration. Energy plays an essential role within the processes of cellular respiration and photosynthesis. SURVEY . 5 and 6. However, plants do not need to eat any food as they make their own food during photosynthesis. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. Learners must make drawings of their leaves at the start of the experiment, indicating the different coloured regions as boiling in alcohol will remove the colour. Repeat this process for two more leaves that were in the well-lit area. This means our breath contains carbon dioxide from respiration. (Solar energy), "What do plants get from the soil that they use for photosynthesis?" 900 seconds . ADP. Write down the seven life processes below. Investigation: Why do bananas become sweeter as they ripen? Teachers may also feel safer if they demonstrate this experiment. The energy wastage occurs during (a) dark reaction (b) photorespiration (c) photosynthesis (d) none of the above Answer: (b) photorespiration 3. Think of an unripe green banana and a ripe yellow banana. [3 marks]. The chlorophyll needs to be removed from the leaf so it does not mask the colour change we expect with the iodine solution. An alternative to a large syringe is to use a bicycle pump or balloon blower. This energy is contained in the chemical bonds of ATP molecules. Fermentation 11.1. ATP synthase, ATP. We have now seen how plants produce food during photosynthesis. In this section, we will be looking specifically at cellular respiration as we will be looking at the chemical reactions which release the energy in food. Use this as a teaching opportunity to help those who cannot do this and when everyone is done compare the different methods used in the class. Learners may get confused and think that because photosynthesis occurs during the day, that respiration only occurs during the night. This process is called respiration. Different people like to learn and study in different ways; some people like to make written summaries, whilst others like to draw their own concept maps when studying and learning. Included are helpful self-reflection and student engagement strategies for current and prospective teachers. You can do this using a table, diagrams or a combination of both. We call these leaves variegated as they have green and white sections. Do you remember using the letters from MRS GREN to help you remember these? To do this you need read the map from top to bottom and have a look at the concepts which come before. The equation for cellular respiration is the direct opposite of photosynthesis. Despite the differences between these two processes, there are some similarities. to personalise content to better meet the needs of our users. Safety warning: remove the needles from the syringes, if there are any, before you hand out the syringes in class. Place half of the plants in the dark for at least 24-48 hours and the others in a well-lit area of the class that is exposed to lots of natural sunlight. The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of cellular respiration breaks down the energy for use. 7. Energy is required for all living things to carry out life processes therefore stored glucose must be converted to energy by respiration. However some sea slugs have learnt to absorb the chloroplasts from the green algae that they eat into their bodies and can actually photosynthesise themselves! Photosynthesis is an endothermic reaction. This helps to remove the waxy cuticle that covers the leaf and breaks down the cell walls. However, in order to store large amounts of glucose, plants need to convert it into compounds which are insoluble in water. Why did they run the rubber tube from Test Tube A to Test Tube B? This specific point was included to allow teachers to reinforce this rule with learners and that we only ever do a taste test if we are sure that a substance is in fact edible. Photosynthesis Respiration Basis of Comparison Location Starting raw materials End products Energy requirement 1. However, respiration does not only produce energy. So how do we test that our breath contains carbon dioxide? Creative Commons Attribution License. The minimum quantum requirement for photosynthesis under optimal conditions is about nine. The benefits of a concept map are that it allows one to show the links between different concepts. pyruvic acid. They will study physiological respiration in Gr. In part 2, learners will need to write up an experimental report. B. Cellular respiration cannot occur without photosynthesis, and photosynthesis certainly cannot occur without the help of its partner. In contrast, cellular respiration is a catabolic process resulting in the breaking down of organic molecules to release energy. First, we want to find out which leaves are able to photosynthesise. Have a look at the concept map below for 'Photosynthesis and Respiration'. Learn. Oxygen is used to break down carbon stored as sugar for energy by the process of respiration. Simply type the link exactly as it is into the address bar in your browser. Remember to take down some notes in the margins of your workbook as you discuss things in class. Only $2.99/month. Hence in photosynthesis you have the light dependent reactions and the dark reactions while in respiration there is aerobic respiration and anaerobic respiration. A) Photosynthesis space is a process in which the energy from light is used to produce carbohydrates. This teacher's guide contains the full version of each concept map. The by-products are carbon dioxide and water. You need to complete the concept map by filling these in. List the two ingredients for respiration. You then need to think back to part 1 and design the method for your investigation. Cellular respiration is a key pathway in energy metabolism (the process of converting food into energy) of all aerobic organisms. The conclusion is that unripe bananas contain more starch than ripe bananas. Photosynthesis and cellular respiration are the life processes performed by most living organisms to obtain usable energy from nature. ADP. Start studying Photosynthesis and Respiration. Sunlight 7 Is there energy released during photosynthesis? Learners must record the items in a bulleted list and take note of measurements. Energy is created during photosynthesis. Therefore the plant converts glucose into starch, which is insoluble in water. Record your observations in a table. Plants are able to photosynthesise because they contain chlorophyll, a green pigment that can capture light energy from the Sun. Do you remember that we spoke about energy for movement (kinetic energy) and energy that is stored (potential energy) in Energy and Change in Gr. Cycle of Oxygen and Carbon Dioxide. Fill in the products of respiration in the block on the left. What are the requirements for photosynthesis to occur? We can test for the products of respiration using our own breath. Learners must take note of what measurements they used. Start studying biology photosynthesis quiz. Respiration occurs in almost all organisms in which glucose is used to make energy … Draw air into the syringe from the atmosphere. Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. As an introduction teachers may want to watch or show the following video to the class: These tables and how to use them are explained in the Teachers' Guide Overview at the front of the book. Photosynthesis takes place in small structures called chloroplasts, which are inside the cells of the leaves and stems of green plants. Others like to make things even more visual, using pictures and diagrams to form their summaries. Do plants undergo photosynthesis and respiration all day and all night? The clear liquid above the solid Ca(OH), Carefully decant as much of this as you need, without stirring up the solid Ca(OH), To make more, simply add more water, shake it up and let it settle again. Energy is needed to sustain life and without it nothing would be able to live on Earth. Glucose will dissolve in water while starch will not dissolve in water. In the summary, we first have the "Key concepts" for this chapter. Which method of testing is better to use and why do you say so? It is important to understand the differences between the two. However, when he tested the leaves, he did not find much glucose, but he did find a lot of starch present. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Pour clear limewater into each beaker until they are half full. - Henry David Thoreau. When they require energy, they can tap the stored energy in sugar by a process called cellular respiration. The process releases oxygen. Our most important source of energy is the Sun. What drives life on Earth and in ecosystems? Plants respire all day and all night. What are the two causes of density in deep current waters? Spell. When this fuel is burned in the presence of oxygen, the chemical potential energy is transferred into light and heat energy. a. salinity (how much salt) of the water and high temperaturesb. The essential requirement of this method is an instrument capable of measuring oxygen or C02 concentration and possessing a rapid response time. Leave the leaf in the alcohol until all the chlorophyll has been removed from the leaf and the alcohol turns green. Some examples of what learners might produce are included here: Aim: To find out which parts of variegated leaves photosynthesise and store starch. What do you think or predict will happen when you conduct this investigation? Photorespiration is a phenomenon that occurs in the cycle (a) Pyruvate (b) Glycolate (c) Hill (d) Krebs Answer: (b) Glycolate 2. Find out why plants that photosynthesise are green. (See reference 2 page 107 ) Photosynthesis, Cellular Respiration, and … [2 marks], What should he have done to make his bean plants grow tall and strong? If you think back to the work you did on fuel and energy in previous grades in Energy and Change, you will remember that fuels, such as wood, coal, and oil, contain chemical potential energy. This was done to allow some plants to photosynthesise and the others not. While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements throug… He was scared that his little brother would knock his tub over, so he hid the tub in his cupboard. Variegated mint-leaf is also very good for this investigation, and is a common plant in Kwa-Zulu Natal. Place a few tablespoons of calcium hydroxide, Ca(OH), Leave the suspension to settle for a few days. Q. This investigation can be done over 2 lessons. As young scientists we also need to question whether this explanation of photosynthesis is accurate. While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration. Photosynthesis and cellular respiration are the life processes performed by most living organisms to obtain usable energy from nature. gcbgc123. After conducting the investigation, you need to write up an experimental report of your findings. The process of photosynthesis starts with the light-dependent reactions before ending in the Calvin cycle. Which substance from the light-dependent reactions of photosynthesis is a source of energy for the light-independent reactions? Animals do not have cellulose for support. Chemically speaking, respiration is photosynthesis in reverse, as you can see in this equation: C 6 H 12 O 6 + 6O 2 → 6H 2 O + 6CO 2 + energy. Hypothesising, investigating, observing, measuring, recording, analysing, writing, group work. If the limewater changed from clear to cloudy white then this would indicate the presence of carbon dioxide. What are some things that have kinetic energy and some that have potential energy? After the leaves are taken from the ethyl alcohol they should be white. What is the end product of photosynthesis and respiration? Plants use sugars (glucose) as a basic molecule from which to make hundreds of other compounds, such as proteins, oils, vitamins, colourful pigments in flowers, strong tasting chemicals (hot chilli plant), sweet tasting nectar and sweet smelling fragrances. The ATP molecules have chemical potential energy in their bonds. Respiration uses oxygen while carbon dioxide and water are given off as by-products. What do plants do with the food that they produce? From Sunlight? You will also learn more about respiration in later grades. Instead animals have something else to provide support and protect the body. Real understanding and knowledge comes from grappling with the subject matter, and not just memorizing facts. The process of photosynthesis involves the use of light energy to convert carbon dioxide and water into sugar, oxygen, and other organic compounds. answer choices . 6 and 7? In National 5 Biology find out how aerobic respiration and fermentation release energy from food to produce the ATP required for cell activity. Let's find out. It also produces water and carbon dioxide as by-products. We will place some pot plants in the light for a day, and some other pot plants in a dark cupboard for a day, and then perform the investigation on the leaves of plants from both groups. You need to design this investigation yourself. [2 marks], Describe the test that the farmer conducted to show that the leaf contained starch.
