- For water to turn into gas it requires heat.
- Heat is supplied by sunlight as it is absorbed by the plant structure.
- Evaporation happens through the stomatal pore.
- Water is delivered into the leaf by the xylem.
- Water vapor diffuses down the diffusion gradient and through the stomatole pore.
