2.53 How water is obsorbed by root hair cells

water uptake in the roots
  • ·      Branches increase the surface area. It also absorbs water.
  • ·      There are root hairs at the end of each root. You have to use microspores to see them. These roots are epidermis cell.
  • ·      Root hair creates the surface area for absorption
  • ·      Involves active transport of mineral + encourage plants to take up water by osmosis/ water moves from dilute to concentrated solution
  • ·      Dilute is a soil of water surrounded the roots + concentrated creates to built up mineral in the cells
  • ·      Water then moves in the plants to the xylem by osmosis. 

Here is an example of a root structure:

  1. active transport create the gradient for osmosis. Dilute in the soil and concentrated in the root.
