Chapter 36.5, Problem 1CC
Summary Introduction
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.

Compare and contrast the forces that move phloem sapand xylem sap over long distances.
Compare the energy needs of a plant for the movement of water in the xylem according to the cohesion-tension model to the movement of phloem sap according to the pressure-flow model?
Consider the pressure flow model of phloem transport. How do sugars and water enter the phloem from the source? How do sugars and water move from one phloem cell to another?
