Describe how cohesion and adhesion contribute to the upward movement of water through a plant.

Cohesive forces makes molecules stick to become a mass. This force ensures that the water molecules stick together to form a mass. This enables water to fill the xylem which is a vascular bundle in plants.

Adhesion forces is what enables the water molecules which are now in form of a single mass to move upward in the columns of the cells for distribution of water and nutrients.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
