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 photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH.

Front

What are light-independent reactions (Calvin Cycle)?

Back

Light-independent reactions, also known as the Calvin Cycle, use ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to produce ATP and NADPH.

Front

What is the significance of water in photosynthesis?

Back

Water is essential in the light-dependent reactions as it is split 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 is glucose used for in plants?

Back

Glucose is used by plants as a source of energy and as a building block for growth and development.
