Question

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

Answer 1

Explanation:

Hlw Mate....

Dark reaction does not mean that it occurs in the absence of light i.e., at night. Infact, it is the reaction occuring simultaneously with light reaction. It a chemical process occurring independent of light. This reaction is completely based on enzymes.

Answer 2

Answer:

Hey mate !

"Do plants undergo dark reaction at night ?" For this question the answer is NO, they don't take place at night

Explanation:

• 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.
• ATP and NADPH combine with CO2 and water to make the end product of glucose.
• The ADP and NADPH+ are recycled to the light-dependent side to start the process over.

That is Dark reactions will fail to continue if the plants are deprived of light for too long since they use the output of the initial light-dependent reactions.
