factors affecting transpiration

Cards (7)

  • what does it mean if a factor increases the water potential gradient
    it will increase teh rate of transpiration
  • what factors decrease the rate of transpiration
    humidity
  • what factors increase the rate of transpiration
    light intensity temperature and wind speed
  • explain how temperature increaes the rate of transpiration
    as temperature increaes the kinetic energy of molecules
  • explain how air speed increases the rate of transpiration
    still air causes a layer of water vapour around the stomata that reduced water loss ,therefore wind speed till prevent the ofrmation of this layer
  • explain how humidty decreases the rate of transpiration
    humidity in the atmosphere decreases the water potential gradient
  • how does light intensity effect the rate of transpiration
    light causes stomata to open and to allow gas exchange for photosynthesis
