Answer:
Ans - 1 Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast.
Ans-2 The dark reactions of photosynthesis occur in the stroma of the chloroplast where they utilize the products of the light reaction. In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose.
Ans-3 The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Both photosystems contain many pigments that help collect light energy, as well as a special pair of chlorophyll molecules in the heart (reaction center) of the photosystem. The special pair of photosystem I is called P700, while that of photosystem II is called P680.
I dont enderstand, u need help about what
A might be it not to sure sorry
