- - - - As it gets hotter, kinetic energy increases the speed of the reaction.
      - If it gets too hot, it stops the reaction.
    - - As it increases, so does the rate of photosynthesis.
      - The light intensity stops increasing at one point.
    - - As it increases, rate of photosynthesis increases.
      - However, at one point another factor will limit the rate of reaction.
    - - The cells of the plant will dehydrate if it doesn't get enough water
- - - - amount of stomata divided by the area of the sample
- - - - Water moves through the xylem into the stem and into the leaves to replace the water lost by evaporation.
        
        Water is lost from the leaves by evaporation by open stomata.
        
        Stomata are openings on the underside of the leaf that allows water vapour out of the plants and carbon dioxide in.
        
        Xylem
        
        Narrow, hollow, dead tubes with lignin, responsible for the transport of water and minerals in plants.
        
        Xylem tissue delivers water from the roots to the leaf
    - - Up to 99% of the water absorbed by roots is lost via transpiration through plant leaves
      - The movement of water from a less concentrated area to a more concentrated area.
  - - - The water molecules move faster when it is warmer so diffusion occurs more rapidly.
      - More stomata opens and water is lost quicker.
    - - This decreases the rate of diffusion and decreases the rate of transpiration
    - - Water that evaporates from the leaves are removed quicker.
      - The water vapour diffuses out of the leaf rapidly, increasing the rate of transpiration.
    - - As it increase, more stomata opens to allow gas exchange. More water vapour can diffuse out, increasing the rate of transpiration
- - - - Useful as all the plant gets an even amount of water
