22N.1A.HL.TZ0.32:
The apparatus is set up to measure the rate of transpiration. As transpiration occurs from the leafy shoot, water is drawn through the apparatus and is measured by timing the movement of the air bubble along the capillary tube.
Which variable(s) must be controlled if transpiration rates are compared in different plant species?
I. Total leaf surface area
II. Volume of water in the reservoir
III. Room temperature
A. I only
B. III only
C. I and III only
D. I, II and III
