Question

1. the below picture shows waters ability for adhesion and cohesion. define adhesion and cohesion and explain why they are important for the plant in the graphic below. 4. describe the property of water being shown below. how do waters hydrogen bonds contribute to this property?

Explanation:

1. Adhesion is the attraction between water molecules and other substances. Cohesion is the attraction between water - water molecules. In plants, adhesion helps water stick to the walls of xylem vessels, while cohesion allows water molecules to stick together in a continuous column, facilitating water transport from roots to leaves against gravity.
2. The property shown is likely surface tension or capillary action (related to cohesion). Water's hydrogen bonds create strong cohesive forces between water molecules. These hydrogen bonds hold water molecules together at the surface, creating surface tension. In capillary action, the cohesive forces between water molecules and adhesive forces between water and the surface of the xylem (or other narrow tubes) work together to pull water up through narrow spaces.

Answer:

1. Adhesion: Attraction between water and other substances. Cohesion: Attraction between water - water molecules. Important for plant water transport as adhesion helps water stick to xylem walls and cohesion forms a continuous water column.
2. The property is related to cohesion (surface tension or capillary action). Hydrogen bonds create strong cohesive forces between water molecules, contributing to surface tension (holding water molecules together at the surface) and capillary action (pulling water up narrow spaces).
