P. Formation of megaspore from the megaspore mother cell by meiosis is called ....I.....
Q. Formation of male gamete from the generative cell by meiosis is called …...II……
Write correct terms for I and II.

Options

A. `{:(I,II),("Microsporgenesis","Fertilization"):}`
B. `{:(I,II),("Microsporgenesis","Gametogenesis"):}`
C. `{:(I,II),("Microsporgenesis","Microporgensis "):}`
D. `{:(I,II),("Gametogenesis","Microsporgenesis"):}`

Answer

To solve the question, we need to identify the correct biological terms for the processes described in statements I and II.

### Step-by-Step Solution:

1. **Understanding Statement I**:
- The statement mentions the formation of megaspores from the megaspore mother cell through meiosis.
- In plants, the megaspore mother cell (also known as the megasporangium) undergoes meiosis to produce megaspores.
- This process is specifically called **Megasporogenesis**.

2. **Understanding Statement II**:
- The second statement refers to the formation of male gametes from the generative cell by meiosis.
- In the context of plant reproduction, the generative cell is part of the pollen grain and undergoes division to form male gametes (sperm cells).
- This process is known as **Microgametogenesis**.

### Final Answer:
- For I: **Megasporogenesis**
- For II: **Microgametogenesis**
