Key learning points

1. Producers make their own food using a process called photosynthesis.
2. Photosynthesis can only happen when there is light.
3. Photosynthesis is a series of chemical reactions that take place inside cells.
4. The reactants of photosynthesis are water and carbon dioxide, and the products are oxygen and glucose (a carbohydrate).
5. Photosynthesis involves many chemical reactions; a word summary of the reactants and products is a model of the process.
