Dark reaction of photosynthesis does not need light. Do plants undergo dark reaction at night? Explain.
Answers
Answer:
Explaination:
▫️ Dark reaction does not mean that it occurs during night time.
▫️ Dark reaction is the next phase after light reaction and it does not require any light.
▫️ The products form during light reaction i.e. ATP and NADPH serve as reactant for dark reaction.
▫️ Dark reaction occurs in Stroma.
▪️ During night time, photosynthesis does not occur, neither light nor dark phase.
Plants respire during night time and give out carbon dioxide.

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