Summary Introduction

To describe: The way by which movement of water in plant is related to water potential.

Introduction: Water is the most crucial factor for a plant to perform its normal cellular functions. The water is absorbed by the roots. The movement of water from the roots to the leaves can be explained using cohesion tension theory of water transport. The water movement from the roots to the vascular tube (xylem) is facilitated by osmosis. Water potential plays an important role in understanding plant physiology because it helps to measure a cell’s ability to absorb water by osmosis.
