Plants take up water from the soil through their roots. Some of the water is used for photosynthesis.

Complete the word equation for photosynthesis. Choose answers from the box.

fat, glucose, nitrogen, oxygen, protein

carbon dioxide + water → ______ + ______

Photosynthesis is the process used by plants, algae, and some bacteria to convert light energy into chemical energy. The word equation summarises the overall process: **Reactants:** The plant takes in carbon dioxide from the air and water from the soil. **Products:** Using light energy (usually from the sun), the plant converts these into glucose and oxygen. - **Glucose** is the sugar used by the plant for respiration (to release energy), and can be converted into other substances like starch for storage or cellulose for building cell walls. - **Oxygen** is released as a waste product into the atmosphere. Therefore, the completed equation is: carbon dioxide + water → glucose + oxygen
