Coelom is filled with botryoidal tissue in

Options

A. tapeworm
B. lugworm
C. leech
D. earthworm

Answer

**Step-by-Step Solution:**

1. **Understanding Coelom:**
- Coelom is a fluid-filled body cavity found in many animals, which is lined by mesoderm. It serves various functions including housing organs and allowing for movement.

2. **Identifying Botryoidal Tissue:**
- Botryoidal tissue is a specialized type of tissue that resembles a cluster of grapes (the term "botryoidal" comes from the Greek word "botryon," meaning "bunch of grapes"). This tissue is involved in the storage of nutrients and may have other functions.

3. **Analyzing the Options:**
- The options provided are:
- A) Tapeworm
- B) Ligworm
- C) Leech
- D) Earthworm

4. **Researching Each Option:**
- **Tapeworm:** A parasitic flatworm that does not have a coelom filled with botryoidal tissue.
- **Ligworm:** This seems to be a typographical error; possibly referring to "lugworm," which also does not have botryoidal tissue.
- **Leech:** Leeches are segmented worms that possess a coelom filled with botryoidal tissue, particularly within their digestive system.
- **Earthworm:** Earthworms have a coelom but do not have botryoidal tissue.

5. **Conclusion:**
- After analyzing the options, it is clear that the coelom filled with botryoidal tissue is found in leeches. Therefore, the correct answer is **C) Leech**.
