Chapter 35.3, Problem 8LO
Summary Introduction
To describe: The pressure-flow model of sugar translocation in phloem.
Introduction: Vascular plants consist of two specialized tissues called as xylem and phloem that act as conducting tubes in plants for the transportation of water and sugar molecules throughout the plant. Phloem vessels are involved in transporting the prepared food (glucose) from leaves to all parts of the plants.

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?
Briefly explain the transpiration-cohesion-tension mechanism in plant
Describe the hypothesis of pressure flow for
the transportation of sugars in the plants.
