Grade 10 Photosynthesis Questions

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the function of stomata in plants?

Back

Stomata are tiny openings on the underside of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What is the role of phloem in plants?

Back

Phloem is the vascular tissue responsible for transporting sugars and nutrients produced during photosynthesis throughout the plant.

Front

What type of energy is required for photosynthesis?

Back

Light energy is required for photosynthesis to convert carbon dioxide and water into glucose.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through the stomata.

Front

What is the significance of leaf age in photosynthesis?

Back

Leaf age can affect the rate of photosynthesis, with younger leaves often being more efficient in photosynthesis than older leaves.

Front

Why can animal cells function without chloroplasts?

Back

Animal cells can function without chloroplasts because they obtain energy by consuming other organisms, rather than producing it through photosynthesis.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
