Spermathecae of Earthworm take part in

Options

A. Collection of sperms of other worm
B. Collection of sperms of the same worm
C. Sperm maturation
D. Fertilization

Answer

**Step-by-Step Solution:**

1. **Understanding Spermathecae**: The spermathecae are specialized structures found in earthworms. They are also known as seminal receptacles.

2. **Location of Spermathecae**: In earthworms, there are four pairs of spermathecae located in segments 6, 7, 8, and 9.

3. **Function During Copulation**: During copulation, the spermathecae collect and store spermatozoa from other earthworms. This is crucial for reproduction.

4. **Nourishment of Sperm**: The ampullae of the spermathecae play a role in nourishing the stored sperm, ensuring they remain viable until fertilization occurs.

5. **Evaluating Options**:
- **Option A**: Collection of sperms from other worms - This is correct because spermathecae store sperm received from other earthworms.
- **Option B**: Collection of sperms from the same worm - This is incorrect as spermathecae do not collect sperm from the same individual.
- **Option C**: Sperm maturation - This occurs in the seminal vesicles located in segments 11 and 12, not in the spermathecae.
- **Option D**: Fertilization - In earthworms, fertilization occurs externally, not within the spermathecae.

6. **Conclusion**: The correct answer is **Option A**: collection of sperms from other worms.
