i. Light Intensity

ii. Carbon Dioxide

iii. Temperature

Sagot :

GinnyAnswer

Final answer:

Light intensity and temperature significantly impact transpiration rates, with higher intensities and temperatures typically leading to increased transpiration. Wind also plays a role in promoting transpiration by removing humid air.


Explanation:

Light intensity affects the rate of transpiration by stimulating stomatal opening, allowing water vapor to leave the leaf, and by warming the leaf, which speeds up transpiration. Higher light intensities generally result in increased transpiration rates.

Temperature also plays a significant role in transpiration. Warmer temperatures cause water molecules to move faster, leading to faster evaporation from stomata. Transpiration rates increase as temperatures rise.

Wind increases transpiration by carrying away humid air, maintaining a dry environment around the leaf and promoting water loss.
