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

Where does photosynthesis occur in plants?

Back

Photosynthesis occurs primarily in the leaves of plants, specifically in the chloroplasts.

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

What is the role of chlorophyll in photosynthesis?

Back

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

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?

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 are the reactants of photosynthesis?

Back

The reactants of photosynthesis are light energy, water (H2O), and carbon dioxide (CO2).

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose (C6H12O6) and oxygen (O2).

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 respiration of most living organisms.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is an energy-carrying molecule produced during the light-dependent reactions, providing energy for the light-independent reactions.
