Explanation:
It allows the cell to control what materials enter and leave.
The energy from cellular respiration comes from food and air. The reactants first cellular respiration are oxygen and glucose. Glucose is a form of sugar and comes from food, and oxygen is found in air.
The main reactants or cellular respiration, as stated above, are oxygen and glucose.

They use them as food and habitats.
