Control group in an experiment does not receive any treatments. It is used as a benchmark to ensure that there is statistical difference in data between the variables of the control and those with treatments. It also ensures that there are no other overlooked factors that have an influence on the experiment that needed to be considered. Having a control group reduces the chances of erroneous conclusions.

<h2><u><em>In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.</em></u></h2>
