2.53 Uptake of Water

2.53- explain how water is absorbed by root hair cells

 Root structure
 Branching pattern occurs, this increases surface area for absorption of water, and also they branch out to find water sources.

The smallest ends of a root are called root hairs (epidermal). The extended (the root hair structure) root hair cell increases absorption of water. When zoomed in the epidermal cells of the roots further illustrate the surface area of the structure concept for the absorption of water.

The plant actively transports the minerals (active transport against the transport movement with the involvement of minerals). This encourages the plant to take up water by the process known as osmosis (water moves from a dilute to a concentrated solution). The dilute solution being the soil water surrounded by root hairs and the concentrated being the minerals in the cell.

It is a two part transportation process. First the active transport of minerals and then the osmosis of water.

Water moves across the cortex of the root to the xylem by osmosis.
