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 are the main products of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

Front

Where does photosynthesis take place in plant cells?

Back

Photosynthesis takes place in the chloroplasts of plant cells.

Front

What is the first step of photosynthesis called?

Back

The first step of photosynthesis is called the light-dependent reactions.

Front

What happens during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is absorbed and converted into chemical energy in the form of ATP and NADPH.

Front

What is the second step of photosynthesis called?

Back

The second step of photosynthesis is called the Calvin cycle or light-independent reactions.

Front

What happens during the Calvin cycle?

Back

During the Calvin cycle, carbon dioxide is fixed and converted into glucose using the ATP and NADPH produced in the light-dependent reactions.

Front

What is the importance of oxygen produced in photosynthesis?

Back

Oxygen produced in photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.
