Temperature

  • Increased temperature makes water evaporate faster, which increases the rate of transpiration.
Illustrative background for HumidityIllustrative background for Humidity ?? "content

Humidity

  • Increased humidity increases the amount of water in the air. This makes it more difficult for more water to evaporate.
  • Increasing humidity decreases the rate of transpiration.

Light intensity

  • Increased light intensity makes water evaporate faster, which increases the rate of transpiration.
Illustrative background for Air flowIllustrative background for Air flow ?? "content

Air flow

  • Increased air flow carries water away from the plant's leaves, encouraging more water to evaporate.
  • Increased air flow increases the rate of transpiration.
