Explanation:

In an experiment to test the effect of fertilizer on plant height, the control group is the baseline for comparison. It consists of plants that do not receive the variable being tested (fertilizer in this case). This allows researchers to determine if any changes in the experimental group (plants with fertilizer) are due to the fertilizer or other factors.
