- - - - Carbon Dioxide + Water react to produce Glucose and Oxygen
- - - - Waxy protective layer that keeps water in and protects from micro-organisms
    - - Stomata is the "mouth" that allows gases to diffuse in or out
      - Guard cells open and close the stomata
        
        Open
        
        Potassium ions enter guard cells via active transport
        
        Water diffuses via osmosis (chasing the potassium which lowered the solvent concentration)
        
        This causes the guard cells to swell, which opens the stomata
        
        Close
        
        Potassium ions leave guard cells via active transport
        
        Water diffuses out via osmosis (chasing the potassium which lowered the solute concentration in the guard cell)
        
        This causes the guard cells to shrink which closes the stomata
      - Stomata allows transpiration to take place
        
        Transpiration is the loss of water vapour through the stomata
  - - - Palisade tissue
        
        Where photosynthesis takes place
        
        On the top layer of the leaf (closest to sun)
      - Spongy mesophyll tissue
        
        Loosely packed; aids in diffusion of carbon dioxide
  - - - Brings water up from roots to leaves
    - - Brings water and dissolved sugars from leaves to rest of plant
