Organelle important in spindle formation during nuclear division is

Options

A. Centriole
B. Golgi body
C. Chloroplast
D. Mitochondrion

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the organelle that is important in spindle formation during nuclear division.

2. **Analyzing the Options**: We have four options to consider:
- A) Centriole
- B) Golgi body
- C) Chloroplast
- D) Mitochondria

3. **Evaluating Each Option**:
- **Option A: Centriole**: Centrioles are part of the microtubule organizing center and play a crucial role in the formation of spindle fibers during cell division. They help in organizing the microtubules that pull the chromosomes apart. Therefore, this option is likely correct.

- **Option B: Golgi Body**: The Golgi body is involved in sorting and packaging proteins but does not play a role in spindle formation. Thus, this option is incorrect.

- **Option C: Chloroplast**: Chloroplasts are involved in photosynthesis in plant cells and do not participate in spindle formation. Therefore, this option is also incorrect.

- **Option D: Mitochondria**: Mitochondria are known as the powerhouse of the cell, generating ATP for metabolic activities, but they do not have a role in spindle formation. Hence, this option is incorrect.

4. **Conclusion**: After evaluating all options, the correct answer is **A) Centriole**, as it is the organelle important in spindle formation during nuclear division.
