Item EB017002: Plants use carbon dioxide and water to make glucose and oxygen.
Word equations can be used to represent chemical reactions. In a word equation, the substances on the left side of the arrow are the reactants, and the substances on the right side are the products. The arrow represents “react to form.”
Reactants → Products
Which of the following word equations describes the reaction that plants use to make glucose (photosynthesis)?
- Minerals + Water → Glucose + Oxygen
- Oxygen + Water → Glucose + Carbon Dioxide
- Carbon Dioxide + Oxygen → Glucose + Water
- Carbon Dioxide + Water → Glucose + Oxygen
