- transpiration is the loss of water through the leaf causd by the evaporation which the water has to be changed from liquid to gas which diffuses through the stomatal pore
- if the concentration gradient of water has a big difference then it has a high rate of transpiration. if the difference is small then it would be a low rate of transpiration
- the factors that would cause a large difference would be- low humidity, high winds, high temperature and high light intensity. This will result in fast diffusion from inside to outside of the leaf
- the rate of transpiration depends on the factors of humidity, wind, temperature and light intensity
the diffusion is caused by the differene in the humidity inside (100%) and outside the leaf (lower than 100%)
