Mitosis is seen in -

Options

A. Apical meristem
B. Lateral meristem
C. lntercalary meristem
D. All meristematic cells

Answer

**Step-by-Step Solution:**

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. It is typically referred to as equational division because the chromosome number remains the same.

2. **Chromosome Number**: Mitosis occurs in diploid (2n) and triploid (3n) cells. This means that cells with two sets of chromosomes (like most somatic cells) and cells with three sets of chromosomes can undergo mitosis.

3. **Location of Mitosis**: Mitosis is primarily observed in meristematic tissues of plants. These tissues are responsible for growth and are found in specific regions of the plant.

4. **Types of Meristematic Tissues**:
- **Apical Meristem**: Located at the tips of roots and shoots, responsible for primary growth.
- **Intercalary Meristem**: Found at the base of leaves or internodes, contributing to the growth of stems and leaves.
- **Lateral Meristem**: Includes the vascular cambium and cork cambium, responsible for secondary growth.

5. **Conclusion**: Since mitosis is seen in all types of meristematic tissues (apical, intercalary, and lateral), the answer to the question is that mitosis is observed in meristematic cells.

**Final Answer**: Mitosis is seen in meristematic tissues, specifically in apical, intercalary, and lateral meristems.
