Which one of the following is associated with cell division ?

Options

A. Microsome
B. Microbody
C. Microtubule
D. Microfibril

Answer

To determine which option is associated with cell division, we can analyze each option provided:

1. **Microzomes**: These are vesicles formed from pieces of the endoplasmic reticulum. They are not directly involved in the process of cell division. Thus, this option is incorrect.

2. **Microbodies**: These are organelles found in various organisms, including plants and animals. They include structures like peroxisomes and glyoxysomes, but they do not play a direct role in cell division. Therefore, this option is also incorrect.

3. **Microtubules**: These are part of the cytoskeleton and play a crucial role in cell division. They are involved in the formation of the mitotic spindle, which helps segregate chromosomes during mitosis and meiosis. This option is correct.

4. **Microfibrils**: These are fine fibrils made up of glycoproteins and cellulose, primarily involved in providing structural support in plant cells. They do not have a direct role in cell division, making this option incorrect.

Based on the analysis, the correct answer is **Microtubules**, as they are directly associated with the process of cell division.

### Summary of the Steps:
1. Analyze each option provided.
2. Determine the role of Microzomes - Incorrect.
3. Determine the role of Microbodies - Incorrect.
4. Determine the role of Microtubules - Correct, as they are involved in cell division.
5. Determine the role of Microfibrils - Incorrect.
