Photosynthesis and respiration

1. Photosynthesis and Respiration

2. PHOTOSYNTHESIS Plants use light energy (for example sunlight) to combine carbon dioxide and water to make simple sugars. Plant cells also release oxygen gas. Once the sugars are formed, they are either used by the plant or stored in the vacuoles . Photosynthesis occurs in the chloroplasts. 6CO 2 + 6H 2 O + Energy --> C 6 H 12 O 6 + 6O 2

3. Aerobic RESPIRATION All organisms, including plants and animals, break down simple sugars into carbon dioxide and water and release energy . The cell uses the energy to build, repair, and reproduce cells. Respiration occurs in the mitochondria of cells. C 6 H 12 O 6  +     6O 2     =     6CO 2    +     6H 2 O  +  Energy
