Photosynthesis

Front

What is photosynthesis?

Back

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

Front

What gas do plants give off during photosynthesis?

Back

Oxygen.

Front

What do plants take in from the air for photosynthesis?

Back

Carbon dioxide.

Front

What is the main sugar produced by plants during photosynthesis?

Back

Glucose.

Front

Which organisms are known to perform photosynthesis?

Back

Green plants, algae, and some bacteria.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is chlorophyll?

Back

Chlorophyll is the green pigment found in plants that absorbs light energy for photosynthesis.

Front

Why are algae important in the process of photosynthesis?

Back

Algae are important because they produce oxygen and serve as a primary food source in aquatic ecosystems.
