Fern sperms (antherozoids) are

Options

A. multicillated or multi flagellated and spirally coiled
B. biciliated and coiled
C. uninucleated and uniflagellated
D. multiciliated sickle shaped

Answer

To answer the question about fern sperms (antherozoids), we will analyze the characteristics of these sperm cells step by step.

### Step-by-Step Solution:

1. **Understanding Antherozoids**:
- Antherozoids are the male gametes produced by ferns, which are classified as pteridophytes. They are essential for reproduction in these plants.

2. **Structure of Antherozoids**:
- Antherozoids are typically characterized by their structure. They are known to be flagellated, which means they have tails that allow them to swim in water.

3. **Cellular Composition**:
- The term "multicellulated" refers to the presence of multiple cells. In the case of fern sperm, they are not simply unicellular; they have a more complex structure.

4. **Motility**:
- Antherozoids are motile, meaning they can move. This is crucial for their function, as they need to swim through water to reach the egg for fertilization.

5. **Flagellation**:
- Fern sperm are flagellated, which means they have one or more flagella (whip-like structures) that aid in their movement.

6. **Correct Answer**:
- Based on the characteristics discussed, the correct description of fern sperms (antherozoids) is that they are "multicellulated or multiflagellated and spiral coiled."

### Final Answer:
Fern sperms (antherozoids) are multicellulated or multiflagellated and spiral coiled.
