Mitosis is absent in

Options

A. Zygote
B. Germinal cell
C. Bone cell
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell. It is an equational division, meaning there is no reduction in chromosome number.

2. **Identifying the Options**: The question provides four options: Zygote, Germinal cell, Bone cell, and None of the above. We need to determine in which of these mitosis does not occur.

3. **Analyzing Germinal Cells**: Germinal cells are involved in the formation of gametes (sperm and eggs). Instead of undergoing mitosis, germinal cells undergo meiosis, which is a different type of cell division that reduces the chromosome number by half, producing haploid gametes.

4. **Evaluating Other Options**:
- **Zygote**: A zygote is formed by the fusion of two gametes and undergoes mitosis to develop into an embryo.
- **Bone Cell**: Bone cells (osteocytes) also undergo mitosis for growth and repair.

5. **Conclusion**: Since mitosis does not occur in germinal cells (as they undergo meiosis), the correct answer to the question is **Germinal cell**.

**Final Answer**: Mitosis is absent in **Germinal cells**.
