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, and releasing oxygen as a byproduct.

Front

What is the chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Front

Which gas is consumed during photosynthesis?

Back

Carbon dioxide (CO₂) is consumed during photosynthesis.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C₆H₁₂O₆), which serves as an energy source for plants.

Front

What is ATP and its role in living organisms?

Back

ATP (adenosine triphosphate) is a molecule that provides energy for various cellular processes in living organisms.

Front

What color of light is least effective for photosynthesis?

Back

Green light is least effective for photosynthesis because it is mostly reflected by plants, rather than absorbed.

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 function of the light-dependent reactions?

Back

The light-dependent reactions convert light energy into chemical energy in the form of ATP and NADPH, and produce oxygen as a byproduct.

Front

What occurs during the Calvin cycle?

Back

During the Calvin cycle, ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide into glucose.
