Photosynthesis-Additional questions HONORS

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 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 do the light-dependent reactions occur?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the primary pigment that absorbs light energy, primarily in the blue and red wavelengths, to initiate photosynthesis.

Front

What is produced during the light-dependent reactions?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle, also known as the light-independent reactions, is the process that converts carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the significance of water in photosynthesis?

Back

Water is split during the light-dependent reactions to release oxygen and provide electrons for the electron transport chain.

Front

What is the equation for photosynthesis?

Back

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

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in the Calvin cycle, where it is fixed into organic molecules to form glucose.
