Multiple Choice

What is the role of cohesion and adhesion in the process of water movement in plants?

• Cohesion helps in water retention

  Adhesion helps in water absorption

• Adhesion helps in water retention

  Cohesion helps in water absorption

• Adhesion holds onto the plant walls (xylem) and cohesion pulls other water molecules up

• Cohesion holds onto the plant walls (xylem) and adhesion pulls other water molecules up

Multiple Choice

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes

• Capillary action caused by both cohesion and adhesion pulls the water up the plant stem.

• Water is pulled by gravity

• Only cohesion causes it to go up the plant.
