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 chloroplasts.

Front

What is the main purpose of the light-dependent reactions?

Back

The main purpose of the light-dependent reactions is to capture energy from sunlight and convert it into chemical energy in the form of ATP and NADPH.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is @@6H_2O + 6CO_2 + sunlight ightarrow 6O_2 + C_6H_{12}O_6@@.

Front

What are the products of the light-dependent reactions?

Back

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

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released during the light-dependent reactions, and is essential for the survival of aerobic organisms.
