2.53 Root Structure

• The root structure has a branching pattern which increases the amount of water absorbed and the surface area of the root.
• There is a root hair in the root that contains of epidermal cells (surface) 
• the root hair concentrates minerals inside the root, which encourages the take of water by osmosis
• osmosis = water enters dilute region and goes to the epidermal cell, concentrated region
• Water travels from the root to the xylem using osmosis
