Photosynthesis 2023

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 Calvin cycle occur?

Back

The Calvin cycle occurs in the stroma of chloroplasts.

Front

What are the main products of the light-dependent reactions?

Back

The main products of the light-dependent reactions are oxygen, NADPH, and ATP.

Front

What role do pigments play in photosynthesis?

Back

Pigments are light-absorbing molecules that capture sunlight for photosynthesis.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.

Front

What factors affect the rate of photosynthesis?

Back

Factors include light intensity, carbon dioxide concentration, temperature, and water availability.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily in the blue and red wavelengths, and plays a crucial role in converting light energy into chemical energy.

Front

What is the significance of the thylakoid membranes?

Back

Thylakoid membranes house the components for the light-dependent reactions of photosynthesis.

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.
