Controlling water loss:

  • A waxy cuticle on the upper and lower surface of the leaf
  • Few stomata
  • Small marrum for the plants that live in dry areas and their stomata are in the inner surface of a rolled leaf
  • Ability to open/close stomata

Transpiration - water loss from a leaf through evaporation and diffusion

1. Root hairs extend between soil particles which greatly increases surface area and takes in water

2. Water and minerals move from all cells through the root until they reach the xylem cells

3. Water and minerals move up through the xylem vessels to…
