During germination, microphyle of seed takes part in

Options

A. Forming weak point for emergence of radicle
B. Absorption of water
C. Passage of gases
D. Leaching inhibitors

Answer

**Step-by-Step Solution:**

1. **Understanding the Micropyle**: The micropyle is a small opening in the seed that is formed from the integuments of the ovule. It plays a crucial role in seed germination.

2. **Role in Germination**: During germination, the micropyle allows water to enter the seed. This is essential for the seed to begin the germination process, as water activates the enzymes needed for growth.

3. **Evaluating the Options**:
- **Option A**: "Forming weak point for emergence of radical" - This is incorrect. The micropyle does not serve as a weak point; rather, it facilitates water absorption.
- **Option B**: "Absorption of water" - This is correct. The micropyle allows water to enter the seed, which is vital for germination.
- **Option C**: "Passage of gases" - This is incorrect. While gas exchange is important, the micropyle is not primarily responsible for this function during germination.
- **Option D**: "Leaching inhibitors" - This is also incorrect. The micropyle does not play a role in leaching inhibitors.

4. **Conclusion**: Based on the analysis of the options, the correct answer is that during germination, the micropyle of the seed takes part in the absorption of water.

**Final Answer**: B. Absorption of water.
