Introduction:
Cohesion and adhesion are two important properties of water that play a crucial role in the functioning of plants. Cohesion refers to the attraction between water molecules, while adhesion refers to the attraction between water molecules and other substances.

Cohesion and Adhesion in Stamen:
The stamen is the male reproductive organ of a flower, consisting of an anther and a filament. Both cohesion and adhesion are found in the stamen of some plants.

Datura:
- Cohesion: In Datura, cohesion is present in the stamen. The water molecules inside the anther and filament are attracted to each other, forming a cohesive force that holds them together.
- Adhesion: Adhesion is also present in Datura stamen. The water molecules within the stamen are attracted to the surrounding tissues, creating an adhesive force that helps to maintain the structure and integrity of the stamen.

Mustard:
- Cohesion: Mustard plants also exhibit cohesion in their stamen. The water molecules within the stamen are attracted to each other, resulting in the cohesive force that holds them together.
- Adhesion: Adhesion is found in Mustard stamen as well. The water molecules within the stamen adhere to the surrounding tissues, providing structural support and stability.

Cotton:
- Cohesion: Cohesion is present in the stamen of Cotton plants. The water molecules within the stamen are attracted to each other, resulting in the cohesive force that holds them together.
- Adhesion: Adhesion is also found in Cotton stamen. The water molecules within the stamen adhere to the surrounding tissues, providing support and maintaining the structure of the stamen.

Tomato:
- Cohesion: In Tomato, cohesion is present in the stamen. The water molecules within the stamen are attracted to each other, resulting in the cohesive force that holds them together.
- Adhesion: Adhesion is also found in Tomato stamen. The water molecules within the stamen adhere to the surrounding tissues, providing support and structural integrity.

Conclusion:
In all the mentioned plants - Datura, Mustard, Cotton, and Tomato, both cohesion and adhesion are found in their stamen. Cohesion helps in keeping water molecules together within the stamen, while adhesion provides support and structural integrity by allowing water molecules to adhere to the surrounding tissues. These properties are essential for the proper functioning of the stamen in plant reproduction.
