When nuclear division takes place without cytoplasmic division, it results in the formation of

Options

A. Polyteny
B. Syncytium
C. Polyploidy
D. Amitosis

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what occurs when nuclear division takes place without cytoplasmic division. This means that the nucleus divides, but the cell does not split into two separate cells.

2. **Analyzing the Options**:
- **Polythene**: This refers to a condition where DNA has replicated multiple times without the separation of the nucleus. It results in a cell with many chromatids but does not specifically refer to the scenario described in the question.
- **Syncytium**: This is a condition where multiple nuclei exist within a single cell due to nuclear division without cytoplasmic division. This is formed when cells fuse or when nuclei divide without the accompanying division of the cytoplasm.
- **Polyploidy**: This refers to cells having more than two paired sets of chromosomes. While it involves nuclear division, it does not specifically relate to the absence of cytoplasmic division.
- **Amytosis**: This is a form of cell division that occurs without mitosis, leading to direct division of the nucleus. It does not involve the scenario of nuclear division without cytoplasmic division.

3. **Identifying the Correct Answer**: Among the options, **syncytium** is the correct answer because it directly describes a condition where nuclear division occurs without cytoplasmic division, resulting in a cell with multiple nuclei.

### Final Answer:
When nuclear division takes place without cytoplasmic division, it results in the formation of **syncytium**.
