Amitosis is shown by

Options

A. Bacteria
B. Hydra
C. Euglana
D. Syllis.

Answer

**Step-by-Step Solution:**

1. **Understanding Amitosis**: Amitosis is a type of cell division that does not involve the typical stages of mitosis (prophase, metaphase, anaphase, and telophase). Instead, it is a simpler form of division where the nucleus divides directly without the formation of chromosomes.

2. **Identifying the Organisms**: The question provides four options: Bacterium, Hydra, Euglena, and Silice. We need to determine which of these organisms undergoes amitosis.

3. **Analyzing Each Option**:
- **Bacterium**: Bacteria are prokaryotic organisms. They reproduce asexually through binary fission, which is a form of amitosis.
- **Hydra**: Hydra is a multicellular organism and a eukaryote. It undergoes mitosis for cell division.
- **Euglena**: Euglena is a unicellular eukaryotic organism that also undergoes mitosis.
- **Silice**: This term is not commonly recognized in biological classification. It might refer to diatoms or silica-based organisms, which are also eukaryotic and undergo mitosis.

4. **Conclusion**: Among the options, only the bacterium (a prokaryote) shows amitosis. Therefore, the correct answer is the first option, Bacterium.

**Final Answer**: Amitosis is shown by Bacterium.
