Question

select the true statements. adhesion between water molecules helps water climb up the sides of xylem cells. gravity exerts a downward force on water moving up through a plant. cohesive forces between water molecules help water molecules stick together as water moves up through a plant. for capillary action to occur, adhesive forces must be stronger than cohesive forces.

Explanation:

• Adhesion between water - xylem cell walls helps water climb up xylem cells.
• Gravity acts downward on water moving up in plants.
• Cohesion keeps water molecules together as water moves up in plants.
• For capillary action, adhesive forces relative to cohesive forces play a role.

Answer:

1. Adhesion between water molecules helps water climb up the sides of xylem cells.
2. Gravity exerts a downward force on water moving up through a plant.
3. Cohesive forces between water molecules help water molecules stick together as water moves up through a plant.
4. For capillary action to occur, adhesive forces must be stronger than cohesive forces.
