Paramecium ingests food through

Options

A. cytoproct
B. cytopyge
C. cytopharynx
D. cytostome

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how Paramecium ingests food. Paramecium is a unicellular organism that belongs to the kingdom Protista.

2. **Identifying the Options**: The options provided are:
- Cytoproct
- Cytopis
- Cytopharynx
- Cytostome

3. **Analyzing Each Option**:
- **Cytoproct**: This is a structure involved in the excretion of waste, not food ingestion. Therefore, it cannot be the correct answer.
- **Cytopis**: This term is not commonly used in the context of food ingestion in Paramecium and seems to be a misnomer in this context.
- **Cytopharynx**: This is a tube-like structure that connects the cytostome to the interior of the cell, but it is not the primary site of food ingestion.
- **Cytostome**: This is the actual "cell mouth" of Paramecium, where food enters the cell. It is the correct structure for food ingestion.

4. **Conclusion**: Based on the analysis, the correct answer is **Cytostome**. This is where Paramecium ingests food.

5. **Final Answer**: Paramecium ingests food through the **Cytostome**.
