A cell divides when its karyocytoplamic index or karyoplasmic index

Options

A. Decreases
B. Increased
C. Restored
D. Remain same

Answer

To solve the question regarding the karyocytoplasmic index and its relation to cell division, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Karyoplasmic Index**:
- The karyoplasmic index (KPI) is defined as the ratio of the volume of the nucleus (karyon) to the volume of the cytoplasm. Mathematically, it can be expressed as:
\[ \text{KPI} = \frac{\text{Volume of Nucleus}}{\text{Volume of Cytoplasm}} \]

2. **Cell Division Process**:
- During cell division (mitosis or meiosis), a cell undergoes significant changes. The nucleus and cytoplasm both undergo division to form two daughter cells.

3. **Changes in Nucleus and Cytoplasm**:
- As the cell prepares to divide, the nucleus undergoes replication, and the cytoplasm also starts to divide. This results in a decrease in the size of the nucleus and the cytoplasm as they are both being partitioned into two new cells.

4. **Effect on Karyoplasmic Index**:
- Since both the nucleus and cytoplasm decrease in size during cell division, the karyoplasmic index will also change. Specifically, because both components are decreasing, the ratio (KPI) will decrease.

5. **Conclusion**:
- Therefore, during cell division, the karyoplasmic index decreases. This indicates that the correct answer to the question is that the karyocytoplasmic index decreases during cell division.

### Final Answer:
The karyocytoplasmic index decreases during cell division.
