ChloroplastsThe food producers of plant cells

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

• Sugars • Oxygen

Steps of Photosynthesis1. 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.
