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

Where does the light-dependent reaction take place?

Back

The light-dependent reaction takes place in the thylakoid membrane of chloroplasts.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that absorbs light energy, which is essential for the photosynthesis process.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, while heterotrophs are organisms that obtain food by consuming other organisms.

Front

What are light-independent reactions also known as?

Back

Light-independent reactions are also known as the Calvin cycle.

Front

What is the significance of carbon dioxide in photosynthesis?

Back

Carbon dioxide is used in the light-independent reactions to help synthesize glucose.

Front

What is the role of water in photosynthesis?

Back

Water provides electrons and protons for the light-dependent reactions and is split to release oxygen as a byproduct.

Front

What is the equation for photosynthesis?

Back

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

Front

What are stomata?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.
