Development of the anther in angiosperms is

Options

A. Leptosporangiate
B. Eusporangiate
C. Gradate
D. Simple

Answer

To solve the question regarding the development of the anther in angiosperms, we will analyze each of the given options step by step.

### Step-by-Step Solution:

1. **Understanding Angiosperms**:
- Angiosperms are flowering plants that possess vascular tissues (xylem and phloem) for the conduction of water and nutrients.

2. **Analyzing the Options**:
- **Option A: Leptosporangiate**:
- In leptosporangiate development, the sporangium is formed from a single epidermal cell. Since angiosperms are multicellular, this option is incorrect.

- **Option B: Eusporangiate**:
- Eusporangiate refers to sporangia that develop from multiple cells and are characteristic of vascular plants. Given that angiosperms are vascular plants, this option is likely correct.

- **Option C: Gradate**:
- The term "gradate" does not pertain to the development of anther in angiosperms. It refers to a gradual change or transition, which is not relevant in this context. Thus, this option is incorrect.

- **Option D: Simple**:
- Simple development refers to the formation from microsporangia, which is more characteristic of lower plants. Since angiosperms are considered higher plants, this option is also incorrect.

3. **Conclusion**:
- After analyzing all the options, the only correct option regarding the development of the anther in angiosperms is **Option B: Eusporangiate**. This is because angiosperms, being vascular plants, exhibit eusporangiate development.

### Final Answer:
The correct answer is **Eusporangiate**.
