Final answer:

The purpose of a control group in an experiment is for comparison to the experimental group to ensure that observed differences are due to the manipulated variable.


Explanation:

The purpose of a control group in an experiment is for comparison to the experimental group. The control group is essential in experiments to eliminate alternate explanations for results and ensure that any differences observed are due to the manipulated variable.

In an example where different fertilizers are applied to tomato plants, the control group would receive no fertilizer, serving as the baseline for comparison to the experimental groups treated with different fertilizers.

Control groups increase the reliability of results by holding certain variables constant, allowing researchers to draw accurate conclusions from their experiments.
