Mitosis taken place in

Options

A. All types of cells except those involved in gamete formation
B. Gonads
C. Axillary buds situated near the apical bud
D. Cells of mature leaf

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 referred to as an equational division because the chromosome number remains constant.

2. **Chromosome Duplication**: Before mitosis occurs, the cell duplicates its chromosomes. This ensures that when the cell divides, each daughter cell receives an identical set of chromosomes.

3. **Types of Cells Involved**: Mitosis occurs in somatic (body) cells, which include all types of cells except those involved in gamete formation.

4. **Gamete Formation**: Cells involved in gamete formation (sperm and egg cells) undergo meiosis, not mitosis. Meiosis is a reductional division that reduces the chromosome number by half, resulting in haploid cells.

5. **Identifying the Correct Answer**: Given the options, mitosis takes place in all types of cells except those involved in gamete formation. Therefore, the correct answer is that mitosis occurs in all cells except those that form gametes.

### Final Answer:
Mitosis takes place in all types of cells except those involved in gamete formation.
