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

Where does photosynthesis occur?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What are the two main reactants of photosynthesis?

Back

The two main reactants of photosynthesis are water (H2O) and carbon dioxide (CO2).

Front

What is produced as a result of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions of photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What happens to water molecules during photosynthesis?

Back

During photosynthesis, water molecules are split into hydrogen and oxygen.

Front

Why is chlorophyll important in photosynthesis?

Back

Chlorophyll is a green pigment in plants that absorbs light energy, which is essential for photosynthesis.

Front

What happens to carbon dioxide during photosynthesis?

Back

Carbon dioxide is absorbed by plants and is used to produce glucose during photosynthesis.

Front

How do plants obtain water for photosynthesis?

Back

Plants obtain water through their roots from the soil.
