The process of formation of pollen grains from PMC through meiosis is called

Options

A. megasporogenesis
B. microsporogenesis
C. parthenogenesis
D. embryogenesis

Answer

To answer the question regarding the process of formation of pollen grains from pollen mother cells (PMC) through meiosis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- Pollen grains are the male gametes in flowering plants.
- Pollen mother cells (PMC) are diploid cells (2n) that undergo meiosis.

2. **Meiosis Process**:
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four haploid cells (n) from one diploid cell (2n).
- In the context of flowering plants, the PMC undergoes meiosis to produce microspores.

3. **Formation of Microspores**:
- The haploid cells produced from the PMC after meiosis are called microspores.
- Each microspore can develop into a pollen grain.

4. **Terminology**:
- The specific term for the process of formation of microspores (and subsequently pollen grains) from PMC is known as "Microsporogenesis".

5. **Conclusion**:
- Therefore, the answer to the question is that the process of formation of pollen grains from PMC through meiosis is called **Microsporogenesis**.

### Final Answer:
The process of formation of pollen grains from PMC through meiosis is called **Microsporogenesis**.
