Question

During seed germination its stored food is mobilized by

• A. Ethylene
• B. Cytokinin
• C. ABA
• D. Gibberellin

Answer 1

The correct option is D Gibberellin

Gibberellin is a type of plant hormone. In seed the stored food is starch Gibberellins stimulate the synthesis of two enzymes i.e protease and α-amylase which are involved in the formation of sugar from starch. The proteases convert an inactive β-amylase to the active form. The active β-amylase and α-amylase together convert starch to glucose which is mobilized to meet the metabolic demands of the embryo during the germination of seed.

So, the correct answer is 'Gibberellin'.
