Which of the following phases do not take place in a cell exhibiting a syncytium?

Options

A. Cytokinesis
B. Karyokinesis
C. Interphase
D. None of these

Answer

To solve the question "Which of the following phases do not take place in a cell exhibiting a syncytium?", we need to understand the concept of syncytium and the phases of cell division.

### Step-by-Step Solution:

1. **Understanding Syncytium**:
- A syncytium is a condition where a cell has multiple nuclei. This occurs when cytokinesis (the division of the cytoplasm) does not happen after mitosis or meiosis, leading to a single cell with multiple nuclei.

2. **Phases of Cell Division**:
- Cell division consists of two main phases: Interphase and M phase (which includes mitosis and cytokinesis).
- Mitosis itself is divided into several stages: Prophase, Metaphase, Anaphase, and Telophase.

3. **Cytokinesis**:
- Cytokinesis is the process that follows mitosis, where the cytoplasm of a parent cell is divided into two daughter cells.
- In a syncytium, cytokinesis does not occur, which means the cell does not divide into separate cells.

4. **Identifying the Phase that Does Not Occur**:
- Since syncytium is characterized by the presence of multiple nuclei within a single cell, the phase that does not take place in a syncytium is **Cytokinesis**.
- All other phases of mitosis (Prophase, Metaphase, Anaphase, and Telophase) still occur, but without cytokinesis, the result is a multinucleated cell.

### Conclusion:
The phase that does not take place in a cell exhibiting a syncytium is **Cytokinesis**.
