Detailed explanation-1: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).

Detailed explanation-2: -The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis. Cellular respiration occurs in plant and animal cells. Plants use sunlight during photosynthesis to convert energy from the sun in order to manufacture sugar and the chemical energy ATP and to release oxygen.

Detailed explanation-3: -Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Detailed explanation-4: -All cells need energy, so all cells do cellular respiration, including both plant and animal cells. The products of cellular respiration are energy (or ATP), carbon dioxide, and water.
