Options

A. megasprogenesis
B. microsporogenesis
C. megagametogeneiss
D. microgametogenesis

Answer

To answer the question, "The process of formation of microspores from pollen mother cell (PMC) through meiosis is called," we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding the Terms**: The question refers to the formation of microspores, which are the precursors to pollen grains. The pollen mother cell (PMC) is the diploid cell that undergoes meiosis to produce these microspores.

2. **Identifying the Process**: The process of forming microspores from the pollen mother cell involves meiosis. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in haploid cells.

3. **Recognizing the Structure**: Microspores are formed in a structure called the microsporangium, which is found in the anther of the flower. The anther is part of the stamen, the male reproductive organ of a flower.

4. **Meiosis in PMC**: In the pollen mother cell, meiosis occurs in two stages:
- **Meiosis I**: The PMC divides to form two haploid cells.
- **Meiosis II**: Each of these two cells divides again, resulting in a total of four haploid microspores.

5. **Naming the Process**: The specific term for the process of forming microspores from the pollen mother cell through meiosis is called "microsporogenesis."

6. **Eliminating Incorrect Options**:
- **Megasporogenesis**: This refers to the formation of megaspores from the megaspore mother cell, which is not relevant here.
- **Megagametogenesis**: This is the formation of the female gametophyte from megaspores.
- **Microgametogenesis**: This refers to the development of male gametophytes from microspores.

7. **Conclusion**: Therefore, the correct answer to the question is "microsporogenesis," as it specifically describes the formation of microspores from the pollen mother cell through meiosis.

### Final Answer:
The process of formation of microspores from pollen mother cell (PMC) through meiosis is called **microsporogenesis**.
