| A | B |
| Food is synthesized (made, stored) | photosynthesis |
| Food is broken down | respiration |
| energy from the sun is stored in glucose | photosynthesis |
| energy of glucose is released | respiration |
| carbon dioxide (CO2) is taken in | photosynthesis |
| carbon dioxide (CO2) is given off | respiration |
| oxygen (O2) is given off | photosynthesis |
| oxygen (O2) is taken in | respiration |
| produces carbohydrates (sugars, glucose, C6H12O6) | photosynthesis |
| produces carbon dioxide (CO2) and water (H20) and yields energy in the form of ATP | respiration |
| requires light energy | photosynthesis |
| does not require light energy | respiration |
| occurs only in plants in the presence of chlorophyll | photosynthesis |
| occurs in all living cells | respiration |
| an energy trapping process that occurs in the chloropast | photosynthesis |
| an energy releasing process that occurs in the mitochondrion | respiration |
