Question

Dark reaction of photosynthesis does not need light. Do plants undergo dark reaction at night? Explain.​

Answer 1

Answer:

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

No,plants do not grow in dark reaction because for the process of photosynthesis light is essential.

Answer 2

Answer:

The cycle of reactions (the Calvin cycle) which occurs in the second phase of photosynthesis and does not require the presence of light. It involves the fixation of carbon dioxide and its reduction to carbohydrate and the dissociation of water, using chemical energy stored in ATP.
