An example of syncytium is

Options

A. Pollen grain formation after meiosis
B. Any normal cell division
C. liquid endosperm in coconut
D. Human zygote

Answer

**Step-by-Step Solution:**

1. **Understanding Syncytium**:
- A syncytium is a type of cell that contains multiple nuclei within a single cytoplasmic mass. This occurs when the cell undergoes repeated nuclear division without cytokinesis, leading to a multinucleated structure.

2. **Analyzing the Options**:
- We need to evaluate each option to determine which one represents a syncytium.

3. **Option 1: Pollen Grain Formation After Meiosis**:
- Pollen grains are formed through meiosis, resulting in haploid cells. Each pollen grain typically contains only one nucleus. Therefore, this option does not represent a syncytium.

4. **Option 2: Any Normal Cell Division**:
- Normal cell division (mitosis) results in two daughter cells, each with a single nucleus. Since there is no formation of multiple nuclei in a single cell, this option is also incorrect.

5. **Option 3: Liquid Endosperm in Coconut**:
- In the case of coconut, the liquid endosperm is formed when the nucleus divides repeatedly without cytokinesis, resulting in a multinucleated structure. This is a classic example of a syncytium.

6. **Option 4: Human Zygote**:
- A human zygote is formed from the fusion of sperm and egg, resulting in a single nucleus. Thus, this option does not qualify as a syncytium.

7. **Conclusion**:
- After analyzing all the options, the correct answer is **Option 3: Liquid Endosperm in Coconut**, as it is the only example that exhibits the characteristics of a syncytium.
