Transpiration Flashcards
1
Q
What are the factors
A
Light temperature humidity and air movement
2
Q
How does light affect transpiration
A
This increases the rate of transpiration- the stomata through which the water evaporates, and only open when photosynthesis is occurring (during light hours)
3
Q
How did temperature affect
A
Increase- increases the kinetic energy, and hence the speed of movement of water molecules= water evaporates more rapidly from the leaves
4
Q
Humidity?
A
the higher the humidity, the gradient is reduced and there is a lower rate of transpiration
5
Q
Air?
A
The faster the air movement, removes the boundary layer
6
Q
Benefits of transpiration?!?
A
Cooling, removal of excess water, and development of root system
