Paper 2: Water Uptake In Plants? Flashcards
1
Q
What can change the rate of water uptake in plants?
A
Environmental factors
2
Q
How can light intensity affect transpiration?
A
High light intensity causes the stomata to open - this increases the rate of evaporation of water from leaf so more water is taken up to replace this
3
Q
How does air movements effect on transpiration?
A
Wind blows moist air away from the stomata keeping the difference gradient high - more air movement, higher transportation rate
4
Q
What affect does temperature have on effects on transpiration?
A
Higher the temperature, more energy water molecules have so they move faster meaning a faster rate of transpiration
