Question #02260

1 Answer

Refer to the explanation.


Photosynthesis consists of light dependent reactions and light independent reactions. The light dependent reactions occur on the thylakoid membranes of the chloroplast. In the light dependent reactions, light strikes the pigment chlorophyll, exciting electrons. which undergo electron transport, releasing #"O"_2"# from water and producing ATP and NADPH. These will be used in the light-independent reactions.

Chloroplasts in plant cells will move in response to light. It is believed they move to maximize light exposure (to increase photosynthesis) but that they can also move away from light which is too intense to avoid being damaged.
