Plants need water for photosynthesis, to keep cells firm, to transport dissolved materials and for cooling when it evaporates off the leaf.  

Plants take up water from soil using roots (which have root hair cells to increase surface area for absorption of water and minerals)

  • water flows up stem into leaves
  • when it evaporates off the leaves it's called transpiration. 
  • flow of water from roots to leaves…
