During microsporogenesis, meiosis occurs in

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding Microsporogenesis**: Microsporogenesis is the process that leads to the formation of microspores, which are the male gametes in flowering plants.

2. **Identifying the Key Cell Type**: The process of microsporogenesis occurs in specific cells known as microspore mother cells (also called pollen mother cells).

3. **Meiosis in Microspore Mother Cells**: During microsporogenesis, the microspore mother cells undergo meiosis. This is a crucial step because meiosis reduces the chromosome number by half, resulting in the formation of haploid microspores.

4. **Formation of Microspore Tetrads**: The result of meiosis in the microspore mother cells is the formation of microspore tetrads. These tetrads consist of four haploid microspores.

5. **Development into Pollen Grains**: Following the formation of microspore tetrads, these microspores can further undergo mitosis to develop into pollen grains, which are the male gametophytes.

6. **Conclusion**: Therefore, the answer to the question "During microsporogenesis, meiosis occurs in?" is the microspore mother cells.

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