• When a photographer takes a photo.
• To get your pictures from the photo lab.
• The process in which plants make their food.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar

Photosynthesis is used to produce food for plants in the form of glucose. In the process, oxygen is released. As shown in the diagram, plants require water and carbon dioxide (from the air). What else is required for photosynthesis and what role does it play?

• Light is required to provide energy for photosynthesis.

• ATP is required as an energy source for photosynthesis.

• Glucose is required as an energy source for photosynthesis

• Oxygen is required to split water molecules in photosynthesis.
