Which is a definition for photosynthesis?
Releasing energy from nutrients
The breaking down of large insoluble molecules into small soluble molecules
The process by which plants make carbohydrates from raw materials using energy from light
The movement of particles from a high concentration to a low concentration
Which is the word equation for photosynthesis?
glucose + oxygen -> carbon dioxide + water
methane + oxygen -> carbon dioxide + water
glucose + carbon dioxide -> oxygen + water
carbon dioxide + water -> oxygen + glucose
State the balanced symbol equation for photosynthesis
