Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (a sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit the plant.

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 of chloroplasts, where sunlight is converted into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle, also known as the light-independent reactions, is the second stage of photosynthesis that occurs in the stroma of chloroplasts, where ATP and NADPH are used to convert carbon dioxide into 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 equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

How does water contribute to photosynthesis?

Back

Water is split during the light-dependent reactions of photosynthesis, providing electrons and protons, and releasing oxygen as a byproduct.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required to drive the chemical reactions of photosynthesis, enabling the conversion of carbon dioxide and water into glucose.
