16. 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, and releasing oxygen as a byproduct.

Front

What are the main products of photosynthesis?

Back

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

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

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

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

Where does the Calvin Cycle take place?

Back

The Calvin Cycle takes place in the stroma of the chloroplasts.

Front

What is the equation for photosynthesis?

Back

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

Front

How does carbon dioxide concentration affect the rate of photosynthesis?

Back

The higher the concentration of carbon dioxide, the greater the rate of photosynthesis, up to a certain point.

Front

What gas is produced during photosynthesis?

Back

Oxygen is the gas produced during photosynthesis.

Front

What is the significance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial for life on Earth as it provides oxygen for respiration and is the foundation of the food chain.
