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
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 highenergy 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
