Question

The ability of water to move up thin tubes, like that of the xylem in plants, is referred to as ________________. This is a result of cohesion and adhesion.

a) Capillarity
b) Osmosis
c) Diffusion
d) Transpiration

Answer 1

The movement of water up thin tubes or xylem in plants due to cohesion and adhesion is known as capillarity, specifically referred to as capillary action.

Step-by-step explanation:

The ability of water to move up thin tubes, like that of the xylem in plants, is referred to as capillarity. This phenomenon occurs as a result of the cohesive force which is the attraction between water molecules, and the adhesive force, the attraction between water molecules and other substances. As water adheres to the walls of the capillary or xylem vessels, it is able to climb against gravity. This upward movement, known as capillary action, is essential for the transport of water and nutrients from the roots to the upper parts of a plant.
