Syncytial or coenocytic epidermis is associated with :

Options

A. Hydra
B. Star fish
C. Earthworm
D. Ascaris

Answer

**Step-by-Step Solution:**

1. **Understand the Terms:**
- The question refers to "syncytial" or "coenocytic" epidermis. This type of epidermis is characterized by the presence of multiple nuclei within a single cell structure.

2. **Analyze the Options:**
- We have four options to consider: Hydra, Starfish, Earthworms, and Ascaris.

3. **Evaluate Each Option:**
- **Hydra:**
- Hydra is a freshwater organism belonging to the phylum Cnidaria. It has a simple body structure and does not possess a syncytial epidermis. Therefore, this option is incorrect.
- **Starfish:**
- Starfish are echinoderms and have a different type of body structure. They do not exhibit syncytial epidermis. Thus, this option is also incorrect.
- **Earthworms:**
- Earthworms belong to the phylum Annelida and have a segmented body with a typical epidermis that does not have multiple nuclei in a single cell. Hence, this option is incorrect as well.
- **Ascaris:**
- Ascaris is a genus of parasitic roundworms. They exhibit a syncytial epidermis, meaning their epidermis has multiple nuclei within a single cell layer. Therefore, this option is correct.

4. **Conclusion:**
- Based on the analysis, the correct answer is **Ascaris**, as it is the only organism listed that has a syncytial or coenocytic epidermis.

**Final Answer:**
- The syncytial or coenocytic epidermis is associated with **Ascaris**.
