During microsporgenesis, meiosis occurs in

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding Microsporogenesis**: Microsporogenesis is the biological process responsible for the formation of microspores, which eventually develop into pollen grains. This process is crucial for plant reproduction.

2. **Location of Meiosis**: During microsporogenesis, meiosis occurs specifically in the Microspore Mother Cells (MMC). These cells are derived from the sporogenous tissue.

3. **Formation of Microspore Mother Cells**: The sporogenous tissue gives rise to microspore mother cells. These cells are diploid (2n) and are the precursors to the haploid pollen grains.

4. **Meiotic Division**: The microspore mother cells undergo meiosis, which is a type of cell division that reduces the chromosome number by half. This reductional division results in the formation of four haploid microspores from each microspore mother cell.

5. **Outcome**: The four haploid microspores produced from meiosis will eventually develop into pollen grains, which are essential for the fertilization process in flowering plants.

**Final Answer**: During microsporogenesis, meiosis occurs in the Microspore Mother Cells (MMC).
