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 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 the primary pigment involved in photosynthesis?

Back

The primary pigment involved in photosynthesis is chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs sunlight and converts it into chemical energy.

Front

What are the products of the light-dependent reactions?

Back

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

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the light-independent stage of photosynthesis 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 oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

What is the equation for photosynthesis?

Back

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