- Factors Affecting The Rate Of Transportation
- Temperature
- The higher the temperature the more kinetic energy in the H2O molecules...(more movement in molecules
- Humidity
- The air inside the leaf is saturated with water vapour, but the humidity surrounding the leaf varies. with values exceeding 70% water potential is great between leaf and atmosphere. (rapid diffusion)
- Air Movement
- Transporationin still air results in the accumulationof a layer of saturated air at the surface of the leaf, this results in a considerable resistance to the diffusion in water through stomata. (lower rate of transpiration)
- Temperature
