Chloroplasts The food producers of plant cells

Plants are the basis for all life on Earth. They make… Sugars Oxygen

Steps of Photosynthesis 1. Sun’s energy hits a chloroplast. Chloroplast = tiny structures in leaf cells

2. Chlorophyll (chemical inside chloroplasts) uses sun’s energy to… Combine Carbon Dioxide and Water. CO² + H²O +

3. Molecular reaction creates sugar and oxygen…

Plant uses sugar for energy. Byproduct Oxygen sent into atmosphere.
