  1. Increase in Light Intensity
    Stomata open to allow gas exchange for photosynthesis, so water vapour can diffuse out of the leaf.
  2. Increase in Temperature
    • Increases the kinetic energy of water molecules so they diffuse faster.
    • Increases the capacity of air to absorb water from leaves.
  3. Decrease in Humidity
    Results in a lower concentration of water molecules outside the leaf making a steeper concentration gradient for diffusion.
  4. Increase in Wind Speed
    Removes water molecules as the pass out of the leaf maintaining a steep concentration gradient of diffusion.
  5. Increase in Light Intensity
