Unit 3, Lesson 6 Root Types, Structures, and Functions

Functions of the Root System

• A. Normally Under the Ground
• Responsible for Anchoring the Plant
• Assists in supplying water and nutrients by drawing it up for the plant.
• Roots take up more space in the soil than does the top part of the plant above ground.
