Comparing rates of transpiration using a potometer

Cards (6)

what does the potometer measure?
the potometer measures the rate of water uptake into a shoot
what is a potometer sometimes called?
its sometimes called a transpirometer, although it doesn't primarily measure transpiration
why is the rate of uptake almost the same as the rate of transpiration?
as most of the water taken up by a leafy shoot is lost through transpiration
what can the potometer be used to measure?
it can be used to measure water uptake by the same shoot under different conditions or can be used to compare the uptake by leafy shoots of different species under the same conditions
what is a potometer?
a device which indirectly measures the rate of water loss during transpiration by measuring the rate of water uptake
what is this a set up of?
a potometer
