Detailed explanation-1: -When conducting an experiment, a control is an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured.

Detailed explanation-2: -A control is something used as a standard of comparison for checking the results of an experiment. A control in this experiment would be a plant that was left out in the sun, under normal conditions, so that you know how much a regular plant would be expected to grow.

Detailed explanation-3: -The group that receives the treatment in an experiment (here, the watered pot) is called the experimental group, while the group that does not receive the treatment (here, the dry pot) is called the control group. The control group provides a baseline that lets us see if the treatment has an effect.

Detailed explanation-4: -controls are essential for the unbiased, objective observation and measurement of the dependent variable in response to the experimental setup.
