Tranpiration Flashcards
1
Q
What is transpiration
A
(of a plant or leaf) the exhalation of water vapour through the stomata.
2
Q
If Temperature Increased
A
Evaporation and diffusion are faster at higher temperatures
3
Q
Humidity Decreased
A
Diffusion of water vapour out of the leaf slows down if the leaf is already surrounded by moist air
4
Q
Wind speed increased
A
Moving air removes water vapour, increasing the rate of diffusion of water vapour from the leaf
5
Q
Light intensity increased
A
The stomata open wider to allow more carbon dioxide into the leaf for photosynthesis
