Factors Affecting the Rate of Transpiration

Vocabulary flashcards reviewing the main environmental factors that affect the rate of plant transpiration based on lecture notes.

Sunlight (in Transpiration)

A factor causing transpiration to be faster during daytime because stomata remain open to allow the inward diffusion of carbon dioxide for photosynthesis.

Stomata at Night

Pores that remain closed during night time, resulting in transpiration hardly occurring.

Temperature (in Transpiration)

A factor that increases the rate of transpiration on hot summer days due to faster evaporation of water.

Wind (in Transpiration)

A factor that increases transpiration when blowing faster because water vapour moves away faster from the surface of leaves.

Humidity

Moisture in the air that reduces transpiration because air cannot hold any water molecules when it is already laden with moisture.
