Question
Under controlled conditions, a transpiration experiment was conducted using two different
plant species, A and B. Each plant species was exposed to a low-humidity environment and
a high-humidity environment with all other conditions kept the same. The transpiration
rate was measured over a period of one hour. The data was graphed as shown below.
