The rate of transpiration can be calculated by measuring the distance travelled by an air bubble in a capillary tube over a given time. The faster the bubble moves, the greater the rate of water uptake – and so the greater the assumed rate of transpiration.

True but googling doesn't help much as half the answers aren't related to the spec meaning it's jargon and not concise compared to student room answers
