In which of the following meiosis takes place

Options

A. Pollen grains
B. Pollen tube
C. Pollen mother cells
D. Generative cells

Explanation

To determine where meiosis takes place among the given options (pollen grains, pollen tube, pollen mother cells, and generative cells), we can analyze each option step by step.

### 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 daughter cells from one diploid parent cell. It is essential for the formation of gametes in sexual reproduction.

2. **Analyzing Pollen Grains**:
- Pollen grains are the male gametes in flowering plants. They are formed from pollen mother cells through meiosis. However, pollen grains themselves do not undergo meiosis.

**Hint**: Pollen grains are the end product of meiosis, not the site where meiosis occurs.

3. **Analyzing Pollen Tube**:
- The pollen tube is a structure that forms after pollen grains germinate. It serves to deliver sperm cells to the ovule. The pollen tube does not undergo meiosis.

**Hint**: The pollen tube is a conduit for sperm delivery, not a site for meiosis.

4. **Analyzing Pollen Mother Cells**:
- Pollen mother cells (microsporocytes) are located in the anthers of flowers. These cells undergo meiosis to produce haploid pollen grains. This is the correct answer as meiosis occurs here.

**Hint**: Look for the cells that directly undergo meiosis to produce gametes.

5. **Analyzing Generative Cells**:
- Generative cells are formed from pollen grains and can undergo mitosis to produce male gametes. They do not undergo meiosis.

**Hint**: Generative cells arise from pollen grains, which are already produced through meiosis.

### Conclusion:
The correct answer to the question "In which of the following meiosis takes place?" is **pollen mother cells**.

### Final Answer:
**Pollen mother cells** are where meiosis takes place.
