What is the significance of stomata in photosynthesis?

• To absorb sunlight for energy conversion.

• To facilitate gas exchange by allowing CO₂ in and O₂ out.

• To transport nutrients throughout the plant.

• To store glucose produced during photosynthesis.

Answer explanation

• Stomata are tiny pores found mainly on the undersides of leaves.

• These pores can open and close, controlling gas exchange between the plant and the atmosphere.

• When open, stomata allow carbon dioxide (CO2) from the air to enter the leaf.

• CO2 is a crucial ingredient for photosynthesis, the process by which plants make their food.

• Stomata also let oxygen (O2), a byproduct of photosynthesis, exit the leaf, completing the gas exchange process.

What are the two products of the light reactions that are needed for the calvin cycle?

• NAD and NADPH

• NADP + and Glucose

• NADPH and ATP

• Oxygen and NADPH

The first molecule formed after CO₂ is added to the Calvin Cycle is:

• RuBP

• 3-PG

• GP3

• G3P

What is the role of the thylakoid membrane in photosynthesis?

• To absorb carbon dioxide from the atmosphere.

• To house the light-dependent reactions.

• To transport glucose throughout the plant.

• To release oxygen as a byproduct.

During which stage of photosynthesis is oxygen produced?

• Calvin cycle

• Electron Chain

• Light dependent

• Light independent

Which statement best describes the light-dependent reactions?

• They require solar energy and produce energy-storing molecules.

• They require solar energy and produce oxygen as the main product.

• They require solar energy and produce simple sugars from carbon dioxide.

• They require solar energy and produce carbon dioxide as the main product.

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
