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 role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the red and blue wavelengths, to drive the photosynthesis process.

Front

What is the chemical formula for water?

Back

H₂O

Front

What is the chemical formula for glucose?

Back

C₆H₁₂O₆

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans, as it is used in cellular respiration.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where light energy is converted into chemical energy in the form of ATP and NADPH.

Front

What is the light-independent reaction (Calvin Cycle) in photosynthesis?

Back

The light-independent reactions, also known as the Calvin Cycle, occur in the stroma of chloroplasts, where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

How do plants store energy produced during photosynthesis?

Back

Plants store energy produced during photosynthesis primarily in the form of glucose (sugar), which can be converted into starch for long-term storage.
