1. In photosynthesis, the light dependent reactions are responsible for the f'~~~.j ~
part of the reaction and in the light independent reactions are responsible for the
~(~(\part of the reaction to from ~~CI.~ ", ~tvco~
2. These processes of these 2 stages of photosynthesis occur in the cllo (tfi>'e:sf of the
plant.
3. In stage 1 of photosynthesis or in the light dependent reaction, the plant is taking
~ energy from the sun in the form of ~htr\br\S and converting it to
chf.m\CA\ energy which is in the form of A:11:> .
