Micropyle of seed facilitates in the entry of:

Options

A. male gametes
B. pollen tube
C. water
D. gases

Answer

To answer the question "Micropyle of seed facilitates in the entry of:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Micropyle**:
- The micropyle is a small opening or pore in the seed coat. It is formed during the development of the ovule and is crucial for the seed's germination process.

2. **Function of the Micropyle**:
- The primary function of the micropyle is to allow the entry of substances into the seed. This is particularly important after the seed has been formed post-fertilization.

3. **Identifying the Options**:
- The options provided are:
- a) Male gamete
- b) Pollen tube
- c) Water
- d) Gases

4. **Analyzing Each Option**:
- **Male Gamete**: This enters the ovule during fertilization, not through the micropyle after the seed has formed.
- **Pollen Tube**: This also enters the ovule before fertilization, not through the micropyle after the seed has formed.
- **Water**: This is the primary substance that enters through the micropyle after the seed has matured. Water is essential for initiating the germination process.
- **Gases**: While gases may diffuse in and out of seeds, they are not specifically facilitated by the micropyle.

5. **Conclusion**:
- Based on the analysis, the correct answer is that the micropyle of the seed facilitates the entry of **water**.

### Final Answer:
The micropyle of the seed facilitates the entry of **water**.
