water uptake in plants Flashcards
1
Q
what environmental factors can change the rate of water uptake in plants?
A
- light intensity
- air movement
- temperature
2
Q
what is a potometer used for?
A
for measuring the rate of transpiration
3
Q
what is the first step of calculating the rate of transpiration using a potometer?
A
- note the position of the air bubble on the capillary tube (ruler)
4
Q
what is the second step of calculating the rate of transpiration using a potometer?
A
- note the position of the bubble on the ruler after a known amount of minuets
5
Q
what is the final step of calculating the rate of transpiration using a potometer?
A
divide the distance moved by the bubble by the time taken
6
Q
what is the equation for the rate of transpiration?
A
distance moved / time taken
