- (b) Why is selectivity of photodynamic treatment very important? How can it be achieved?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. A B transpiration rate (pl/cm²min) с 0.2 0.18 0.16 0.14 0.12 0.1 0.08 0.06 A bar graph of the transpiration rates of two plants under different humid conditions D 0.04 0.02 low humidity 40% In order to see the effect the change in humidity had on the transpiration rate, what would be a proper con trol to add to the study? high humidity 80% running the same experiment multiple times to collect additional data adding more water to the original plants and running the experiment again grow another set of plants at normal humidity growing more plants at 0% and 100% humidity Species A Species BUnder controlled conditions, a transpiration experiment was conducted using two different plant species, A and B.
