Concept explainers
To explain: Comparison of the forces that helps in movement of phloem sap and xylem sap over long distances.
Concept introduction: Sap is substance that is transported in a plant by its phloem and xylem. The xylem and phloem constitute the vascular tissue of the plant which mainly helps to transport water, sugars, and other substances that are important for the plant. Gravity and suction work in opposite directions in water columns, but water molecules are held together by cohesive forces in water columns and water moves in upward direction due to the transpiration pull which is much stronger than the gravitational forces.
