Meiosis occurs in

Options

A. Endosperm cells
B. Intercalary meristems
C. Apical meristems
D. Spore mother cells.

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells from one diploid cell. It is essential for sexual reproduction and occurs in specific types of cells.

2. **Identifying Cell Types**: The question asks where meiosis occurs. To answer this, we need to identify the types of cells involved in meiosis:
- **Endosperm Cells**: These are triploid cells that undergo mitosis, not meiosis.
- **Meristem Cells (Intercalary and Apical)**: These cells also divide by mitosis to promote growth in plants.
- **Spore Mother Cells**: These are diploid cells that undergo meiosis to produce haploid spores.

3. **Conclusion**: Based on the analysis, meiosis occurs in spore mother cells. These cells undergo meiosis to produce haploid spores, which are crucial for the life cycle of plants and fungi.

4. **Final Answer**: Therefore, the correct answer to the question "Meiosis occurs in" is **spore mother cells**.
