what is emasculation ? Why and when is it done ?

Explanation

### Step-by-Step Solution:

1. **Definition of Emasculation**:
- Emasculation is the process of removing the male reproductive part, specifically the anther, from a bisexual flower in plants. This is done to prevent self-pollination.

2. **Purpose of Emasculation**:
- The primary reason for emasculation is to avoid self-pollination. In a bisexual flower, the presence of both male (anther) and female (stigma) reproductive organs can lead to self-fertilization. By removing the anther, the chances of self-pollination are minimized.
