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 chemical equation for photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

Glucose and oxygen.

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 photosynthesis.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled space inside the chloroplast where the Calvin cycle takes place.

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 significance of light energy in photosynthesis?

Back

Light energy is essential for converting carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into glucose.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to produce ATP and NADPH, while light-independent reactions (Calvin cycle) use ATP and NADPH to synthesize glucose.
