Microtubules are found in

Options

A. bacteria
B. eukaryotic cells
C. prokaryotic cells
D. microvilli

Answer

**Step-by-Step Solution:**

1. **Understanding Microtubules**: Microtubules are hollow, tube-like structures made of tubulin protein. They are part of the cytoskeleton, which helps maintain the shape of the cell.

2. **Identifying the Options**: The question asks where microtubules are found. The options provided include bacteria, eukaryotic cells, prokaryotic cells, and microvilli.

3. **Analyzing Each Option**:
- **Bacteria**: Bacteria are prokaryotic cells and do not contain microtubules. They have a simpler structure and do not require microtubules for shape maintenance.
- **Eukaryotic Cells**: Eukaryotic cells have a complex structure and contain microtubules as part of their cytoskeleton. This is a strong candidate for the correct answer.
- **Prokaryotic Cells**: Similar to bacteria, prokaryotic cells do not have microtubules. They lack the cytoskeletal structures found in eukaryotic cells.
- **Microvilli**: Microvilli are extensions of the cell membrane and are primarily made up of microfilaments, not microtubules.

4. **Conclusion**: Based on the analysis, microtubules are found in eukaryotic cells. Therefore, the correct answer is eukaryotic cells.

**Final Answer**: Microtubules are found in eukaryotic cells.
