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 Structure**: Anthers are part of the stamen in flowering plants and are responsible for producing pollen grains, which are the male gametophytes. They consist of four layers: epidermis, endothelium, middle layer, and tapetum.

2. **Dehiscence Definition**: Dehiscence refers to the process by which anthers release pollen grains. This occurs when the anther walls break open.

3. **Types of Dehiscence**: There are several types of dehiscence observed in angiosperms:
- **Transverse Dehiscence**: The anther splits across its width, allowing pollen to be released from the sides.
- **Longitudinal Dehiscence**: The anther splits along its length, releasing pollen from the top.
- **Valvular Dehiscence**: The anther has valve-like structures that open to release pollen.
- **Apical Pore Dehiscence**: Pollen grains are released through pores located at the tip of the anther.

4. **Most Common Type**: Among these types, the apical pore dehiscence is the most common type found in most angiosperms. This type allows for efficient release of pollen grains through small openings at the apex of the anther.

5. **Conclusion**: Therefore, the answer to the question is that the most common type of dehiscence of anther found in most angiosperms is **apical pore dehiscence**.
