In Lycopodium the antherozoids are

Options

A. Biflagellate
B. Multiflagellate
C. Multiciliate
D. Non motile

Answer

**Step-by-Step Solution:**

1. **Understanding Lycopodium**: Lycopodium is a genus of vascular plants that belong to the group of clubmosses. They are part of the plant kingdom and are known for their unique reproductive structures.

2. **Identifying Antherozoids**: Antherozoids are male gametes produced in the reproductive structures of plants. In Lycopodium, these gametes are crucial for the fertilization process.

3. **Shape of Antherozoids**: The antherozoids in Lycopodium are described as pear-shaped. This characteristic shape is important for their identification.

4. **Flagella Presence**: The antherozoids of Lycopodium are biflagellate, meaning they possess two flagella. These flagella are located at the anterior end of the antherozoid, which aids in their motility.

5. **Comparison with Other Plants**: The biflagellate antherozoids of Lycopodium are more similar to those found in bryophytes (like mosses) than to those in vascular plants such as pteridophytes, gymnosperms, or angiosperms.

6. **Evaluating Options**:
- The first option states that the antherozoids are pear-shaped and biflagellate, which is correct.
- The second option suggests they are multi-flagellate, which is incorrect since they only have two flagella.
- The third option mentions multi-ciliate, which is also incorrect as they do not have cilia; they only have flagella.
- The last option states they are motile, which is true, but it does not accurately describe their structure.

7. **Conclusion**: Therefore, the correct description of the antherozoids in Lycopodium is that they are pear-shaped and biflagellate.

**Final Answer**: In Lycopodium, the antherozoids are pear-shaped and biflagellate.
