What statement is true about microspore of angiosperms

Options

A. Resultant of mitotic division
B. First cell of gamophytic generation
C. Resultant of double fertilization.
D. First cell of endosperm.

Answer

To determine the true statement about the microspore of angiosperms, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Microspore**:
- Microspores are the male gametophytes in angiosperms, commonly known as pollen grains. They are produced in the anthers of flowers.

2. **Evaluating Option A**:
- "Resultant of a mitotic division": This statement is incorrect. Microspores are formed from meiosis, not mitotic division.

3. **Evaluating Option B**:
- "First cell of a gametophytic generation": This statement is correct. The microspore develops into the male gametophyte (pollen grain) and represents the first cell of the gametophytic generation in angiosperms.

4. **Evaluating Option C**:
- "Resultant of a double fertilization": This statement is incorrect. Double fertilization occurs after the microspore has developed into a pollen grain and has fertilized the ovule.

5. **Evaluating Option D**:
- "First cell of the endosperm": This statement is also incorrect. The endosperm is formed after fertilization and is not related to the microspore.

6. **Conclusion**:
- The most accurate statement about the microspore of angiosperms is that it is the "first cell of a gametophytic generation". Therefore, the correct answer is **Option B**.

### Final Answer:
**Option B: First cell of a gametophytic generation.**
