transport through the leaves

• xylem vessels transport the water all around the plant.

  • at the leaves, water leaves the xylem and moves into the cells mainly by the apoplast pathway
• • water evaporates from the cell walls once water has entered it after leaving the xylem and into the spaces between the cells
• when the stomata open water evaporates - it diffuses out of the leaf, down the water potential gradient and into the surrounding air
• stomata


  tiny pores in the surface of the leaf
• transpiration


  the evaporation of water from a plants surface
• water loss from a leaf

  
• water passes from the xylem into the leaf cells by osmosis ( down its water potential gradient)
