1. Science Bellwork 1. How are plants able to survive without taking in food? Photosynthesis: plants use the energy of sunlight to make food 2. What is the function of the mitochondria? Which cell is it found in? Most of cell’s energy is produced here In plant AND animal cells

2. Cellular Respiration All organisms, including plants, break down simple sugars (glucose) for energy. – Eukaryotes: takes place in mitochondria. – Prokaryotes: takes place in cytoplasm.

3. Part 2: How it works Glucose (sugar) is combined with oxygen to release energy Produces carbon dioxide and water as waste products Allows your muscles to move, keeps body warm, allows you to grow

4. Part 3: Formula Glucose + O 2  Energy + CO 2 + Water

5. Comparing Cellular Respiration to Photosynthesis Photosynthesis: Sun (Energy) + Carbon dioxide + Water  Glucose + Oxygen Cellular Respiration: Glucose + Oxygen  Energy + Carbon Dioxide + Water
