Name Key Class Date The Reactions of Photosynthesis This section explains what happens inside chloroplasts during the process of photosynthesis. Inside a Chloroplast 1. Chloroplasts contain saclike photosynthetic membranes called thylakoids 2. What is is a granum? A single stack of thylAKOIDS, is suspended in the stromn of the chloropins) 3. The region outside the thylakoid membranes in the chloroplasts is called the StromA LA. thick Fluis found inside the inner membrane of7 the chloroplast 4. What are the two stages of photosynthesis called? a. Light Dependent 5. Complete the illustration of the overview of photosynthesis by writing the products and the reactants of the process, as well as the energy source that excites the electrons. Nane C Date The Chloroplast In plants, photosynthesis talous place in chloroplats. Inside chloro plasts are saclike membranes called thylakoids. These thylakoids are arrangod in stacko. A stack of thylakoida is called a gran. The region outside of the thylakoids, but inside the chloroplast is called the streama In the dingsure of the chiloroplant, Abel a thylakoid, he stroma, auf the gen Stroma Thy lakers Chloroplast Guanym Armaer the following questions. Ciride the arrect answer 1. Where am the phonosystems, or light-collecting units of photosynthesis, found? thylakoid membranes froma 2. In what part of the chloroplast does the Cabin cycle take place? thylakoid membranes 3. In what part of the chiamplast do the light-dependent mactions of photosynthesis take plane? thylakoid membranes Name Key Class Date Chapter 8 Photosynthesis Vocabulary Review Completion Use the words below to fill in the blanks with terms from the chapter. ATP light-dependent reactions autotroph photosynthesis Calvin cycle photosystem chlorophyll stroma heterotroph thylakoid 1. An organism that obtains its energy from the foods it eats is a(an) Hetertroph 2. During the reaction's •Light-dependent reactor phe of photosynthesis, energy from sunlight is used to form ATP, NADPH, and oxygen. 3. ATP is one of the main chemical compounds that cells use to store and release chemical energy. 4. A light-collecting unit in a chloroplast is a photosystem 5. The light-dependent reactions of photosynthesis take place in the thy la Koin membranes of chloroplasts. 6. The stage of photosynthesis that uses ATP and NADPH to form high-energy sugars is the Calvin Cycle. 7. A plant or other organism that is able to make its own food is a(an) Autotroph 8. Photosynthesis is the overall process in which sunlight is used to convert carbon dioxide and water into oxygen and high-energy sugars. 9. The region of the chloroplast in which the Calvin cycle occurs is the Stroma 10. The principle pigment in plants is called -Chlorophy 11 Name Key Class Date 11. Circle the letters of the regions of the visible spectrum in which chlorophyll absorbs light very well. blue-violet region b. green region c. red region d. yellow region
