Frequently asked questions

What is the difference between transpiration and evaporation?

Evaporation is water turning to vapour from any surface, such as a puddle or a lake. Transpiration is specifically water leaving a living plant through its stomata, and the plant can control it by opening and closing those pores. Scientists often combine the two as 'evapotranspiration'.

Why is transpiration important?

It creates the suction that draws water and dissolved minerals up from the roots, cools the leaves, and returns huge volumes of water to the atmosphere. Forests move so much water this way that they influence regional rainfall.

When does transpiration happen fastest?

When it is hot, dry, bright and windy, because the stomata are open for photosynthesis and the surrounding air carries the vapour away quickly. It slows at night and in humid, still conditions.
