Question
Chapter 44, Problem 13RQ
Summary Introduction
To describe:
The movement of sugars in phloem and explain the movement of phloem fluid up and down in the plant.
Introduction:
Phloem is tissue that transports photosynthetic product or its analogs from one part of the plant to another. The xylem tissues transport water and nutrients from roots to leaves in a unidirectional manner, whereas phloem allows the movement of sap where it is required.
