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 is the primary function of chlorophyll?

Back

Chlorophyll is the pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

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 chemical equation for photosynthesis?

Back

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂.

Front

What are the raw materials needed for photosynthesis?

Back

The raw materials needed for photosynthesis are carbon dioxide (CO₂) and water (H₂O).

Front

What gas is produced as a byproduct of photosynthesis?

Back

Oxygen (O₂) is produced as a byproduct of photosynthesis.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy required to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What are thylakoids?

Back

Thylakoids are membrane-bound structures within chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the function of 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 produced in the light-dependent reactions.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing the energy needed for various biochemical reactions, including those in photosynthesis.
