WHAT DO YOU MEAN BY A "SUITABLE CONTROL" IN AN EXPERIMENT?
WHAT WOULD BE THE "SUITABLE CONTROL" IN AN EXPERIMENT TO INVESTIGATE THE EFFECTS OF DIFFERENT LIGHT INTENSITIES ON RATE OF PHOTOSYNTHESIS?

In an experiment, a "suitable control" refers to a group or condition that lacks the variable being tested or manipulated. Its purpose is to serve as a baseline or reference point for comparison to the experimental group, which is the group or condition where the variable is present.
In the case of investigating the effects of different light intensities on the rate of photosynthesis, a suitable control would be a group or condition that is exposed to a constant or normal light intensity. This control group should receive the same conditions, such as temperature, water, and CO2 levels, as the experimental group. The control group is important because it allows researchers to accurately compare and analyze the results of the experimental group by demonstrating what happens when no changes are made to the variable being investigated.
By setting up a control group with a constant or normal light intensity during the experiment, researchers can observe the changes in the rate of photosynthesis in the experimental group when different light intensities are introduced. This comparison helps determine the specific effect of the varying light intensities on the rate of photosynthesis.
