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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in the chloroplasts of plants that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

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

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis during the light-dependent reactions and is essential for the respiration of most living organisms.

Front

What is the main source of energy for photosynthesis?

Back

The main source of energy for photosynthesis is sunlight.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the equation for photosynthesis?

Back

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