Transcription

1 The Chloroplast In plants, photosynthesis takes place in chloroplasts. Inside chloroplasts are saclike membranes called thylakoids. These thylakoids are arranged in stacks. A stack of thylakoids is called a granum. The region outside of the thylakoids, but inside the chloroplast is called the. In the diagram of the chloroplast, label a thylakoid, the, and the granum. thylakoid Chloroplast granum Answer the following questions. Circle the correct answer. 1. Where are the photosystems, or light-collecting units of photosynthesis, found? 2. In what part of the chloroplast does the Calvin cycle take place? 3. In what part of the chloroplast do the light-dependent reactions of photosynthesis take place? 76

2 Photosynthesis Overview Photosynthesis uses light energy to convert water and carbon dioxide into oxygen and high-energy sugars. The picture below shows an overall view of the process of photosynthesis. Use the words below to label the diagram. Calvin cycle light energy sugars light-dependent reactions oxygen water carbon dioxide light energy NADP + ADP + P light-dependent reactions Calvin cycle NADPH oxygen sugars Use the diagram to answer the questions. 1. Finish the equation for photosynthesis. light carbon dioxide water sugars oxygen 2. Which of the following is also called the light-independent reactions of photosynthesis? Circle the correct answer. Calvin cycle 77

3 Photosystems I and II Photosystems I and II are important parts of the light-dependent reactions of photosynthesis. In photosystem II, light energy is absorbed by electrons. These high-energy electrons are then passed down an. The electrons are then passed to photosystem I. In photosytem I, the electrons are reenergized by light energy and used to make NADPH. Color the diagram according to the prompts below. Color the two places where light energy enters the reactions yellow. Color the hydrogen ions red. Color the electrons green. Color the thylakoid membrane blue. (yellow) (yellow) Inner thylakoid space 2 H 2 O 4 + O 2 e- e- e- (blue) photosystem II photosystem I e- 2 NADP NADPH Use the diagram to answer the questions. 1. Where does light energy enter the system? in photosystems I and II 2. What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane? Circle the correct answer. photosystem II 78

4 Formation in the Light-Dependent Reactions of Photosynthesis In the light-dependent reactions of photosynthesis, the electron transport chain transports hydrogen ions across the thylakoid membrane. synthase uses these hydrogen ions to power the formation of. Hydrogen ions move through synthase and cause it to spin. As it spins, it forms from ADP and a phosphate. Color the arrow that shows how synthase spins. Then, draw in the formation of from ADP. Hydrogen ion Inner Thylakoid Space Thylakoid Membrane Synthase Stroma ADP Use the diagram to answer the question. Circle the correct answer. 1. Where does the formation of take place? inner thylakoid space 79

5 The Calvin Cycle and NADPH are both produced by the light-dependent reactions of photosynthesis. The Calvin cycle uses the energy in and NADPH to produce high-energy sugars. Circle the places where and NADPH are used. Then, draw an X over the 6-carbon high-energy sugar produced by the Calvin cycle. Calvin Cycle 6 C CO 2 6 C C ADP NADPH 6 ADP NADP Sugars and other compounds Use the diagram to answer the question. 1. How many molecules of carbon dioxide are used to produce one 6-carbon sugar molecule? six 2. What is formed as a result of the Calvin cycle? Circle the correct answer. six-carbon sugar carbon dioxide 80
