Male gametes of bryophytes are :-

Options

A. Multiflagellated
B. Uniflagellated
C. Non-motile
D. Biflagellated

Answer

**Step-by-Step Solution:**

1. **Understanding Bryophytes**: Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. They reproduce via gametes.

2. **Identifying Male Gametes**: The male gametes in bryophytes are called anthrozoids.

3. **Production of Male Gametes**: These anthrozoids are produced in a specialized structure known as the antheridium.

4. **Characteristics of Male Gametes**:
- Male gametes (anthrozoids) are motile, which means they can move.
- They possess flagella, which are whip-like structures that aid in locomotion.

5. **Type of Flagellation**:
- The male gametes of bryophytes are specifically biflagellated, meaning they have two flagella.
- This is crucial for their movement towards the female gametes for fertilization.

6. **Eliminating Incorrect Options**:
- **Multiflagellated**: This would imply more than two flagella, which is incorrect.
- **Uniflagellated**: This means having one flagellum, which is also incorrect.
- **Non-motile**: This suggests no flagella and inability to move, which is not true for anthrozoids.

7. **Conclusion**: The correct answer is that the male gametes of bryophytes are biflagellated.

**Final Answer**: Male gametes of bryophytes are biflagellated.
