Front

Why are plants usually green?

Back

Because the chlorophyll reflects green light.

Front

What are the raw materials of photosynthesis?

Back

Carbon dioxide and water.

Front

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

Back

It gradually slows down to zero because CO2 is used up.

Front

What is the chemical formula for carbon dioxide?

Back

CO2.

Front

Chlorophyll absorbs a higher percentage of which colors of light?

Back

Red and blue.

Front

What is photosynthesis?

Back

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

Front

What is the main product of photosynthesis?

Glucose.

Front

What gas do plants release during photosynthesis?

Back

Oxygen.

Front

What role does chlorophyll play in photosynthesis?

Back

It absorbs light energy, primarily from the red and blue wavelengths.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
