Answer
| Photosynthesis | Respiration |
|---|---|
| Photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen. | Respiration uses oxygen and glucose to power the activities of the cell. |
| Photosynthesis results in gain of dry weight of the plants. | Respiration results in loss of dry weight of the plants. |
| The raw materials for the photosynthesis are water, carbon dioxide and sunlight. | The raw material for respiration is glucose. |
| Photosynthesis occurs in plants and some photosynthetic bacteria. | Respiration occurs in all living organisms. |
