A student wanted to determine the rate of transpiration by using a potometer, as shown. The student was asked to calculate a transpiration value with the units $\text{mm}^3$, $\text{m}^{-2}$ and $\text{hour}^{-1}$. Which measurements would the student need to make?
- Avolume of water in the reservoir, length of the capillary tubing, temperature and how many leaves are on the shoot
- Bvolume of water in the reservoir, radius of the capillary tubing, time and surface area of the leaves
- Cdistance air bubble moves, radius of the capillary tubing, time and surface area of the leaves
- Ddistance air bubble moves, length of the capillary tubing, temperature and how many leaves are on the shoot
