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 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 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

Where does the light-independent reaction (Calvin cycle) occur?

Back

The light-independent reactions occur in the stroma of the chloroplasts.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the primary function of the mesophyll in leaves?

Back

The mesophyll is the tissue in leaves where most photosynthesis occurs, containing chloroplasts.

Front

What is the significance of stomata in photosynthesis?

Back

Stomata are small openings on the leaf surface that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.

Front

What is the equation for photosynthesis?

Back

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

Front

What is carbon fixation?

Back

Carbon fixation is the process of converting inorganic carbon (CO2) into organic compounds during the light-independent reactions.
