Explain the role of stomata in the process of photosynthesis.

They absorb sunlight

They allow the exchange of gases

They store glucose

They transport water

Answer explanation

Stomata are small openings on leaves that facilitate gas exchange. During photosynthesis, they allow carbon dioxide to enter and oxygen to exit, which is essential for the process to occur effectively.

What is the chemical equation for photosynthesis?

Answer explanation

The correct equation for photosynthesis is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This shows that carbon dioxide and water are converted into glucose and oxygen using sunlight.

Describe how plants store excess glucose produced during photosynthesis.

As proteins

As starch

As fats

As oxygen

Answer explanation

Plants store excess glucose produced during photosynthesis primarily as starch. Starch serves as a compact energy reserve that can be broken down into glucose when needed, unlike proteins or fats, which serve different functions.
