Answer this question

Answer this question Word dark reaction for biosynthetic phase of photosynthesis is misnomer word because . (1) Dark reaction occur during dark ark reaction occur during day Dark reaction is completely free from light (4) Dark reaction occur during short dark intervals

Dear student,

The biosynthetic phase of photosynthesis does not directly depend on the presence of light but is dependent on the products of the light reaction which are ATP and NADPH. The biosynthetic process starts immediately after light becomes unavailable and continue for some time, and then stops. If light available for sometimes and becomes again unavailable the process of biosynthesis starts again.

Therefore, the dark reaction occurs during short dark intervals.

The correct option is (4).

The dark reactions are a misnomer because they don’t require darkness; they are merely light-independent... so, ANS = (2) DARK REACTION OCCUR DURING DAY .
