Special features of the endothecium of anther of Capsella:
Answer: D. All of the above.
The endothecium of Capsella anther exhibits radial elongation, thickening of cellulose walls, and hygroscopic properties. These features are important for the proper development and release of pollen grains. The radially elongated cells allow for efficient pollen production and dispersal. The thickened cellulose walls provide structural support and protect the developing pollen from mechanical damage. The hygroscopic nature of the endothecium helps in maintaining the required humidity levels within the anther, which is essential for pollen viability. Therefore, all of these features contribute to the effective functioning of the anther in Capsella.
- Radially elongated: The endothecium cells of the anther in Capsella are elongated in a radial direction. This arrangement allows for efficient pollen development and release.
- Thickening of cellulose: The endothecium cells possess thickened cellulose walls. This thickening provides structural support to the anther and helps in preventing mechanical damage during pollen development and release.
- Hygroscopic: The endothecium cells of Capsella anther are hygroscopic, meaning they have the ability to absorb and release moisture. This feature helps in maintaining appropriate humidity levels within the anther, which is crucial for optimal pollen development and viability.

Special Features of the Endothecium of Anther of Capsella
- Radially elongated: The endothecium of Capsella's anther is radially elongated, which means it has elongated cells that are arranged in a radial pattern around the anther.
- Thickening of cellulose: The endothecium of Capsella's anther has thickening of cellulose in its cell walls. This thickening provides structural support to the anther and helps in the dehiscence of the anther during pollen release.
- Hygroscopic: The endothecium of Capsella's anther is hygroscopic, meaning it has the ability to absorb and retain moisture. This property is important for maintaining the proper moisture levels within the anther for pollen development and release.
- All of the above: Therefore, all of the mentioned features - radially elongated cells, thickening of cellulose, and hygroscopic nature - are unique characteristics of the endothecium of anther of Capsella. These features play important roles in the development and function of the anther in this plant species.
