Centrosome is

Options

A. a nuclear structure of animal cell
B. cytoplasmic structure of only animal cells
C. cytoplasmic structure of both plant and animal cells
D. cytoplasmic structure of plant cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Centrosome**: The centrosome is a structure found in cells that plays a crucial role in cell division. It is important to determine its characteristics and location.

2. **Identifying the Options**: The question provides four options regarding the nature of the centrosome:
- Option A: A nuclear structure of animal cell.
- Option B: Cytoplasmic structure of only animal cell.
- Option C: Cytoplasmic structure of both plant and animal cell.
- Option D: Cytoplasmic structure of plant cell.

3. **Eliminating Incorrect Options**:
- The centrosome is not found in plant cells; it is specific to animal cells. Therefore, options C and D can be eliminated.

4. **Determining the Correct Structure**:
- The centrosome is located in the cytoplasm, near the nucleus, and is not a nuclear structure. This means that option A can also be eliminated.

5. **Final Conclusion**:
- Since the centrosome is a cytoplasmic structure that is found only in animal cells, the correct answer is **Option B: Cytoplasmic structure of only animal cell**.

**Final Answer**: Option B: Cytoplasmic structure of only animal cell.
