Part A Match the terms below with the correct description

Chlorophyll Grana Photosynthesis Chloroplast Light-dependant reactions Photosystem Electromagnetic spectrum Light-independent reactions Stroma Electron transport chain Photon Thylakoid

a. ______packet of solar energy b. ______energy-capturing portion of photosynthesis that takes place in thylakoid membranes of chloroplasts and cannot proceed without solar energy, it produces ATP and NADPH c. ______green pigment that absorbs solar energy and is important in photosynthesis found in the thylakoid membrane. d. ______large, central compartment in a chloroplast that is fluid filled and contains enzymes used in photosynthesis e. ______membrane-bounded organelle with chlorophyll – containing membranous thylakoids; where photosynthesis takes place f. ______Photosynthetic unit where solar energy is absorbed and high-energy electrons are generated; contains a pigment complex and an electron acceptor g. ______Passage of electrons along a series of carrier molecules form a higher to a lower energy level; the energy released is used for the synthesis of ATP. h. ______Process usually occurring within chloroplasts whereby chlorophyll traps solar energy and carbon dioxide is reduced to a carbohydrate. i. ______Series of photosynthetic reactions in which carbon dioxide is fixed and reduced in the chloroplast. j. ______Synthesis portion of photosynthesis that takes place in the stroma of chloroplasts and does not directly require solar energy; it uses the products of the light dependant reactions to reduce carbon dioxide to a carbohydrate
