Question

The rate of water uptake is approximately equal to the rate of transpiration. An increase in wind speed increases the rate of transpiration. Suggest the effect that increasing wind speed would have on the movement of the air bubble.

Answer 1

Explanation:

The potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water.
