Porogamy refers to entry of pollen tube through…..

Options

A. integuments
B. chalaza
C. micropyle
D. stigma

Answer

**Step-by-Step Solution:**

1. **Understanding Porogamy**: Porogamy is a type of fertilization process in plants where the pollen tube enters the ovule through a specific part.

2. **Identifying the Entry Point**: The options provided are:
- Integuments
- Chalaza
- Micropyle
- Stigma

3. **Analyzing Each Option**:
- **Integuments**: These are the outer layers of the ovule and are not the entry point for porogamy.
- **Chalaza**: This is the part of the ovule opposite the micropyle, and in chalazogamy, the pollen tube enters here, not in porogamy.
- **Micropyle**: This is the opening in the ovule through which the pollen tube enters in porogamy.
- **Stigma**: This is the part of the flower where pollen grains land, but it is not where the pollen tube enters the ovule.

4. **Conclusion**: Based on the analysis, in porogamy, the pollen tube enters through the micropyle.

5. **Final Answer**: Therefore, the correct answer is **Micropyle**.
