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 role do chloroplasts play in photosynthesis?

Back

Chloroplasts are organelles in plant cells that contain chlorophyll and are responsible for capturing light energy to convert carbon dioxide and water into glucose during photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange; they enable carbon dioxide to enter the leaf and oxygen to exit.

Front

Where does the light-dependent reaction of photosynthesis occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for the light-dependent reactions of photosynthesis, which convert light energy into chemical energy.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily in the blue and red wavelengths, and is essential for photosynthesis.

Front

What is the significance of oxygen produced during photosynthesis?

Back

Oxygen produced during photosynthesis is released into the atmosphere and is essential for the survival of aerobic organisms, including humans.
