Photosynthesis Review Worksheet
Part A
Match the terms below with the correct description
Chlorophyll
Chloroplast
Electromagnetic spectrum
Electron transport chain
Grana
Light-dependant reactions
Light-independent reactions
Photon
Photosynthesis
Photosystem
Stroma
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
Part B
