During microsporogenesis, meiosis occurs in

Options

A. endothecium
B. microspore mother cells
C. microspore tetrads
D. pollen grains

Answer

**Step-by-Step Text Solution:**

1. **Understanding Microsporogenesis**: Microsporogenesis is the process of formation of microspores from microspore mother cells (also known as pollen mother cells). This process is crucial for the development of male gametes in flowering plants.

2. **Identifying the Key Process**: The key process in microsporogenesis is meiosis, which is a type of cell division that reduces the chromosome number by half, resulting in the formation of haploid cells.

3. **Locating Where Meiosis Occurs**: In flowering plants, meiosis occurs specifically in the microspore mother cells (MMC). These cells are located within the microsporangium (the pollen sac) of the anther.

4. **Formation of Microspores**: After meiosis, the microspore mother cells divide to form four haploid microspores, which are arranged in a cluster known as a tetrad.

5. **Development into Pollen Grains**: Once the microspores are formed, they eventually separate and develop into pollen grains as the anther matures and dehydrates.

6. **Conclusion**: Therefore, the correct answer to the question is that meiosis occurs in the microspore mother cell during microsporogenesis.

**Final Answer**: Meiosis occurs in the microspore mother cell during microsporogenesis.
