Transport in plants

HideShow resource information

Water is an important compound in plants. It is necessary for:

  • photosynthesis, as a raw material
  • support, to keep cells firm and turgid(turgor)
  • for transport of mineral ions
  • a solvent

Movement of water through a plant

Water enters roots by osmosis and moves along cells until it reaches a xylem, which carries it to the plant.

Transpiration - the Los of water through the leaves

The transpiration stream - the continuous flow of water, into, through and out of the plant.

Measuring transpiration - using a potometer
