Select an incorrect statement regarding male gametophyte in angiosperms

Options

A. Absence of antheridia
B. Highly reduced
C. Presence of sperm
D. Exosporic nature

Answer

To solve the question regarding the incorrect statement about male gametophyte in angiosperms, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Angiosperms**:
- Angiosperms are flowering plants that produce seeds. They are characterized by the presence of flowers and fruits.

2. **Defining Male Gametophyte**:
- The male gametophyte in angiosperms is represented by pollen grains. These grains are responsible for producing male gametes (sperms).

3. **Analyzing the Statements**:
- **Option A**: "Absence of antheridia"
- Antheridia are male reproductive structures found in algae, fungi, and non-flowering plants. In angiosperms, antheridia are absent.
- **Conclusion**: This statement is **correct**.

- **Option B**: "Highly reduced"
- Pollen grains (the male gametophyte) are indeed highly reduced structures in angiosperms.
- **Conclusion**: This statement is **correct**.

- **Option C**: "Presence of sperms"
- Male gametophytes in angiosperms do produce sperms.
- **Conclusion**: This statement is **correct**.

- **Option D**: "Exosporic nature"
- Exosporic refers to the condition where the male gametophyte is capable of producing both male and female gametes. In angiosperms, the male gametophyte does not produce female gametes; it only produces male gametes (sperms).
- **Conclusion**: This statement is **incorrect**.

4. **Final Answer**:
- The incorrect statement regarding male gametophyte in angiosperms is **Option D**: "Exosporic nature".
