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 primary function of chloroplasts?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the chemical reactions that convert carbon dioxide and water into glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the respiration of most living organisms.

Front

What is the main pigment involved in photosynthesis?

Back

Chlorophyll is the main pigment that absorbs light energy for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where does the light-dependent reaction occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is converted into glucose using ATP and NADPH.
