Chapter 7 Flashcards
captures light energy from the sun and converts it to chemical energy stored in sugars and other organic molecules
photosynthesis
equation for photosynthesis
water + carbon dioxide + light energy -> glucose + oxygen
carbon dioxide enters plants through
pores in the leaf called stomata
photosynthesis occurs in
chloroplasts
structure of chloroplast
stroma, thylakoid membrane, grana, inner and outer membranes
where are chlorophyl molecules embedded
inner thylakoid membrane
what is the primary function of plant pigments
absorb solar energy
why are leaves green
chlorophyll molecules absorb violet-blue and red ligh but reflect or transmit green-yellow light
process of light dependent reactions
chlorphyll absorbs solar energy and ejects an electron, which is passed down an electron transport chain and water is split releasing O2
requirements for light dependent reactions
H20, ADP, and NADP+
products of light reactions
O2, and the energy storing compounds ATP and NADH
what is fixed during the calvin cycle
carbon dioxide
what is the product of the calvin cycle
G3P which can be used to make glucose
is an adaptation fro hot and dry weather
C4 photosynthesis
examples of C4 plants
corn, sugar cane
