How does temperature, light intensity and wind affect transpiration?

Answer
- Temperature — Higher temperatures increase the rate of transpiration due to faster evaporation of water.
- Light intensity — With Sunlight the rate of transpiration is faster as stomata are open to allow inward diffusion of carbon dioxide for photosynthesis. During night time, the stomata remain closed and hence transpiration hardly occurs.
- Wind — Transpiration is more when the wind is blowing faster as water vapour moves away faster from the surface of leaves.
