Every cell in your body carries out cellular respiration to produce energy from food. Plant cells also carry out cellular respiration. During cellular respiration, both plants and animals give off carbon dioxide. 1 sugar molecule C6H12O6 Cellular Respiration Plants make sugar during photosynthesis. They produce oxygen and water as waste products. Oxygen and water leave the plant through openings in the leaves called stomata. Plants give off oxygen when light energy is available. 6 carbon dioxide molecules 6CO2 Photosynthesis Name Date STUDENT RESOURCE 5.2 INFORMATION SHEET
