Select the odd one

Options

A. Pollen grain
B. Antipodal cell
C. Synergids
D. Egg cell

Answer

To solve the question of selecting the odd one out from the given options: pollen grain, antipodal cells, synergids, or egg cells, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Pollen grain
- Antipodal cells
- Synergids
- Egg cells

2. **Understand the Definitions**:
- **Pollen Grain**: This is the male gametophyte, which is responsible for the male reproductive function in flowering plants.
- **Antipodal Cells**: These are part of the female gametophyte, specifically located at the opposite end of the embryo sac.
- **Synergids**: These are also part of the female gametophyte and are located near the egg cell, assisting in fertilization.
- **Egg Cells**: These are the female gametes found in the female gametophyte.

3. **Categorize the Options**:
- **Male Gametophyte**: Pollen grain
- **Female Gametophyte**: Antipodal cells, synergids, and egg cells

4. **Determine the Odd One Out**:
- Since pollen grain is the only option that is part of the male gametophyte, while the other three (antipodal cells, synergids, and egg cells) are components of the female gametophyte, pollen grain is the odd one out.

5. **Conclusion**: Therefore, the odd one out is **Pollen Grain**.

### Final Answer:
**Pollen Grain** is the odd one out.
