Photosynthesis

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 is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What are the main reactants of photosynthesis?

Back

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

Front

What are the products of photosynthesis?

Back

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

Front

What is the overall equation for photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the significance of light in photosynthesis?

Back

Light provides the energy needed to drive the chemical reactions of photosynthesis, allowing plants to convert CO2 and H2O into glucose.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split during the light-dependent reactions to release oxygen and provide electrons for the process.

Front

What is the function of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in photosynthesis that is absorbed from the atmosphere and used to produce glucose.

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes of chloroplasts, where light energy is converted into chemical energy (ATP and NADPH).
