Which type of dehiscence of anther is found in most of the Angiosperms ?

Options

A. Transverse
B. Longitudinal
C. Valvular
D. By apical pores

Answer

**Step-by-Step Solution:**

1. **Understanding Anther Dehiscence**: The anther is a part of the stamen in flowering plants that produces pollen grains, which are the male gametes. The process by which anthers release pollen is known as dehiscence.

2. **Types of Dehiscence**: There are several types of dehiscence observed in anthers:
- **Transverse Dehiscence**: This type involves the anther splitting across its width.
- **Longitudinal Dehiscence**: This type involves the anther splitting along its length.
- **Valvular Dehiscence**: In this type, the anther opens through a slit along the sides.
- **Apical Pore Dehiscence**: This type involves the anther opening at the top through a small pore.

3. **Identifying the Most Common Type**: Among these types, longitudinal dehiscence is the most commonly observed in most angiosperms. This is because it allows for efficient release of pollen grains, ensuring successful fertilization.

4. **Conclusion**: Therefore, the type of dehiscence of the anther that is found in most angiosperms is **longitudinal dehiscence**.
