Front

What is the correct equation for photosynthesis?

Back

CO₂ + light + H₂O → O₂ + Sugar

Front

What happens to the rate of photosynthesis if a plant is enclosed in an air-proof bottle?

Back

Gradually slows down to zero because CO₂ is used up.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What are the main products of photosynthesis?

Back

Oxygen and glucose.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to convert CO₂ and H₂O into glucose.

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).

Front

What is the significance of photosynthesis to life on Earth?

Back

It produces oxygen and organic compounds that are essential for life.
