Paper 2: Water Uptake In Plants?

Question 1

What can change the rate of water uptake in plants?

Answer 1

Environmental factors

Question 2

How can light intensity affect transpiration?

Answer 2

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

Question 3

How does air movements effect on transpiration?

Answer 3

Wind blows moist air away from the stomata keeping the difference gradient high - more air movement, higher transportation rate

Question 4

What affect does temperature have on effects on transpiration?

Answer 4

Higher the temperature, more energy water molecules have so they move faster meaning a faster rate of transpiration
