Item SB061001: Plants use glucose to build larger molecules (polymers) that make body structures (and water molecules)
A word equation can be used to represent chemical reactions. The substances on the left side of the arrows are the starting substances, and the substances on the right side are the ending substances. The arrow represents “react to form.”
Which of the following word equations describes the reaction plants use to make the molecules needed to build body structures like stems and leaves?
- Glucose → Carbohydrate Polymer + Water
- Glucose + Oxygen → Carbon Dioxide + Water
- Glucose + Minerals → Carbohydrate Polymer
- Glucose + Nitrogen → Protein Polymer
