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

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment that absorbs sunlight for photosynthesis.

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 light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

What is produced during the light-dependent reactions?

Back

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

Front

What is the role of ATP in photosynthesis?

Back

ATP provides the energy needed for the light-independent reactions (Calvin Cycle) to synthesize glucose.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the light-independent reactions, is the process where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of chloroplasts.

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths, which is essential for driving the photosynthesis process.

Front

What is the equation for photosynthesis?

Back

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