The site of meiosis in higher plants-

Options

A. Growth cells
B. Root tip cell
C. Stomatal cell
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 and is essential for sexual reproduction. It occurs in specific cells that are involved in the formation of gametes or spores.

2. **Identifying the Options**: The question provides four options regarding the site of meiosis in higher plants:
- Option 1: Growth cells
- Option 2: Root tip cells
- Option 3: Stomatal cells
- Option 4: Spore mother cells

3. **Evaluating Option 1 (Growth Cells)**: Growth cells are involved in increasing the number of cells through mitosis, not meiosis. Therefore, this option is incorrect.

4. **Evaluating Option 2 (Root Tip Cells)**: Root tip cells contain meristematic tissues that are responsible for growth and cell division through mitosis. Meiosis does not occur here, making this option incorrect as well.

5. **Evaluating Option 3 (Stomatal Cells)**: Stomatal cells, also known as guard cells, are involved in the regulation of gas exchange (CO2 and water vapor) in plants. They do not undergo meiosis, so this option is also incorrect.

6. **Evaluating Option 4 (Spore Mother Cells)**: Spore mother cells (also known as microsporocytes or megasporocytes, depending on whether they produce male or female spores) are the correct site of meiosis in higher plants. They undergo meiosis to produce spores, which can develop into gametes.

7. **Conclusion**: Based on the evaluation of all options, the correct answer is **Option 4: Spore Mother Cells**.
