Question

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

Answer 1

Hello...

Dark reaction :

➡Dark reaction includes both

C3 and C4 pathway.

➡This is also called as

biosynthetic phase.

➡The reactions of the dark

reaction occurs in stroma.

Do plants undergo dark reaction only at night?

✨Dark reaction does not mean that it only occurs in night. ✨

✨This process does not depend directly on the presence of light. it also occur even in the absence of light .✨

✨But it is dependent on the products of light reaction i.e ATP and NADPH ✨

" so we should not say that dark reaction occurs only night "

⏩it depends on the products of light reaction but not on the sunlight ⏪

HI MATE...... ❤

Dark reaction of photosynthesis does not occur because at night there is insufficient supply of carbon dioxide, a plant cannot photosynthesize, even in the presence of light
