In angiosperms, microsporogenesis and megasporogeneis

Options

A. occur in anther
B. form gametes without further divisions
C. involve meiosis
D. occur in ovule

Answer

### Step-by-Step Solution:

1. **Understanding Microsporogenesis and Megasporogenesis:**
- Microsporogenesis is the process by which microspores (pollen grains) are formed from microspore mother cells (microsporocytes) in the anthers of flowers.
- Megasporogenesis is the process by which megaspores are formed from megaspore mother cells (megasporocytes) in the ovules of flowers.

2. **Location of Processes:**
- Microsporogenesis occurs in the **anther** of the stamen.
- Megasporogenesis occurs in the **ovule** of the ovary.

3. **Cell Division Type:**
- Both processes involve **meiosis**.
- In microsporogenesis, the microspore mother cells undergo meiosis to produce four haploid microspores.
- In megasporogenesis, the megaspore mother cells also undergo meiosis to produce four haploid megaspores, but typically only one of these survives to develop into the female gametophyte.

4. **Formation of Gametes:**
- The microspores produced in microsporogenesis will develop into pollen grains, which are the male gametes.
- The megaspores produced in megasporogenesis will develop into the female gametophyte (embryo sac), which contains the egg cell.

5. **Conclusion:**
- The correct answer to the question regarding microsporogenesis and megasporogenesis in angiosperms is that both processes involve meiosis.

### Final Answer:
The correct option is **C: involve meiosis**.
