True!- Without a control group you have nothing to compare your experimental data with... so you cannot prove anything.
An example:
If you wish to test if a mutant plant grows better than a wildtype plant. You couldn't just grow the mutant plant and say it's better or worse than the wildtype if you haven't grown the wildtype plant aswell.
