Ответ:
This relates to the problem question of the experiment. I believed the problem question should have been something like:
What is the effect of sunlight over plant growth.
When an experiment is design, the variables should be maintain constant. So if you want to test the effect of sunlight o the effect of a certain chemical this should be applied to the same type of plants in order to be able to compare and also to be sure the different data is in fact caused by what is being tested and not caused by the organism.
