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 can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding Anther Development**: The anther is a crucial part of the stamen in flowering plants (angiosperms) where pollen grains are produced. The development of the anther involves several stages and structures.

2. **Identifying Types of Sporangia**: The question presents different types of sporangia: Leptosporangiate and Eusporangiate.
- **Leptosporangiate**: This type of sporangium develops from a single epidermal cell and is typically found in ferns, not in angiosperms.
- **Eusporangiate**: This type refers to sporangia that develop from multiple cells and is characteristic of vascular plants, including angiosperms.

3. **Analyzing the Options**:
- **Leptosporangiate**: Not applicable to angiosperms as they do not develop from a single epidermal cell.
- **Eusporangiate**: This is the correct option as angiosperms are vascular plants and their anthers develop from multiple cells.
- **Gradate**: This term refers to a gradual change or transition and does not relate to the development of anther.
- **Simple**: This option refers to microsporangia or small spores, which are not representative of the anther development in angiosperms.

4. **Conclusion**: Based on the analysis, the correct answer regarding the development of the anther in angiosperms is **Eusporangiate**.

### Final Answer:
The development of the anther in angiosperms is **Eusporangiate**.
