2.53) Uptake of Water

•  The roots have branching areas which increase the surface area for greater absorption of water, and along the branches there were root hairs for same purpose.
• Root hairs are the epidermal cell formed by the extension of cell wall.
•  Firstly, roots get minerals from the soil into the root hair by active transport. The intake of minerals makes it more concentrated inside than the outside.
• Water then is absorbed by osmosis into the root hairs. (Remember, is the movement of water from area with greater concentration to area with lesser concentration.)
• Water then moved out from the root cells and into the xylem.
