During seed germination, its stored food is mobilised by

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding Seed Germination**: Seed germination is the process where a seed develops into a new plant. This involves breaking dormancy and initiating growth.

2. **Role of Hormones**: During germination, various hormones play crucial roles. One of the key hormones involved is gibberellin.

3. **Function of Gibberellin**: Gibberellin is responsible for hastening the maturity of seeds. It triggers the process that leads to the mobilization of stored food within the seed.

4. **Hydrolytic Enzymes**: Gibberellin stimulates the synthesis of hydrolytic enzymes. These enzymes are crucial because they break down the stored food reserves in the seed.

5. **Food Reserves in Seeds**: The primary food reserve in many seeds is the endosperm. The hydrolytic enzymes act on the endosperm, breaking it down into simpler compounds that can be utilized by the developing plant.

6. **Outcome of Mobilization**: As the stored food is mobilized, it provides the necessary nutrients for the seed to germinate and grow into a small plantlet.

7. **Conclusion**: Therefore, during seed germination, the stored food is mobilized by gibberellin through the action of hydrolytic enzymes.

### Final Answer:
During seed germination, its stored food is mobilized by gibberellin.
