Trichocysts are found in

Options

A. Ectoplasm of euglena
B. Ectoplasm of paramecium
C. Endoplasm of euglena
D. Endoplasm of paramecium

Answer

**Step-by-Step Solution:**

1. **Understanding Trichocysts**: Trichocysts are specialized structures found in certain protozoans, particularly in the cortex of ciliated and flagellated protozoa. They are involved in defense and capturing prey.

2. **Identifying Locations**: The question asks where trichocysts are found. The options given are:
- Ectoplasm of Euglena
- Ectoplasm of Paramecium
- Andoplasm of Euglena
- Endoplasm of Paramecium

3. **Analyzing Each Option**:
- **Ectoplasm of Euglena**: Euglena is a flagellated protozoan, but it does not have trichocysts.
- **Ectoplasm of Paramecium**: Paramecium is a ciliated protozoan known to have trichocysts located in its ectoplasm.
- **Andoplasm of Euglena**: Euglena does not have trichocysts, so this option is incorrect.
- **Endoplasm of Paramecium**: Trichocysts are specifically located in the ectoplasm, not the endoplasm.

4. **Conclusion**: The correct answer is that trichocysts are found in the ectoplasm of Paramecium.

**Final Answer**: Trichocysts are found in the ectoplasm of Paramecium.
