Factors affect Transpiration

• High temperature

  • Increases rate of transpiration -> more water molecules evaporate and rate of diffusion of water from the leaf increases
• Increased airflow

  • Increases transpiration
  • removes water molecules off the leaf's surface
  • faster rate of diffusion
  • Steeper gradient concentration
• Increased light intensity

  • Increases transpiration
  • Stomata is open for longer meaning more water is lost
• High humidity

  • decreases transpiration
  • less steep concentration gradient
  • Slow diffusion rates
