Photosynthesis
- Plants use light energy (for example sunlight) to combine carbon dioxide (CO2) and water (H2O) to make simple sugars (C6H12O6).
- Plant cells also release oxygen gas (O2).
- Once the sugars are formed, they are either used by the plant or stored in the vacuoles.
- Photosynthesis occurs in the chloroplasts.
Respiration
- All organisms, including plants and animals, break down simple sugars (C6H12O6) into carbon dioxide (CO2) and water (H2O) and release energy.
- The cell uses the energy to build, repair, and reproduce cells.
- Respiration occurs in the mitochondria of cells.
