1. Water Movement in Plants
Water moves up the xylem of plants due to the 5 functions/forces.
Transpirational pull
Adhesion
Cohesion
Capillarity
Osmotic pressure

2. Transpirational pull: water evaporates from the leaves and creates an upward pull felt along the xylem (using a straw)

3. Adhesion: the attraction of unlike molecules that cause water molecules to be attracted to the walls of xylem tubes

4. Cohesion: the polarity of water molecules causes an attraction between water molecules which helps pull up water in the xylem

5. Capillarity: the ability of water to easily move up a tube because it is narrow compared to a very wide tube

6. Osmotic pressure: difference in pressure that builds because the endodermis lets water in but not out
