Photosynthesis Quiz

What is the role of chlorophyll in photosynthesis?

• Regulates the temperature of the plant during photosynthesis

• Absorbs light energy and converts it into chemical energy

• Produces oxygen and releases it into the atmosphere

• Reflects light energy and prevents it from reaching the plant

Why is chlorophyll important for photosynthesis?

• It has no role in photosynthesis.

• It releases light energy and converts it into chemical energy.

• It absorbs light energy and converts it into chemical energy.

• It absorbs chemical energy and converts it into light energy.

What are the products of the light-dependent reactions in photosynthesis?

• ATP and NADPH

• Glucose and Oxygen

• ADP and NADP+

• Carbon Dioxide and Water

Explain the process of light-dependent reactions in photosynthesis.

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

• Light-dependent reactions occur in the nucleus of the cell.

• Light-dependent reactions take place in the mitochondria.

• Light-dependent reactions happen in the cytoplasm of the cell.

What is the role of light-independent reactions in photosynthesis?

• Break down glucose to release energy

• Produce oxygen as a byproduct

• Absorb sunlight to produce ATP

• Convert carbon dioxide into glucose

How do light-independent reactions contribute to the overall process of photosynthesis?

• Release energy from sunlight

• Convert carbon dioxide into glucose

• Produce oxygen as a byproduct

• Convert water into carbon dioxide

Write the chemical equation for photosynthesis.

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

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

• 6CO2 + 6H2O → C6H12O6 + 6O2

• 6CO2 + 6H2O + heat energy → C6H12O6 + 6O2

Explain the significance of the photosynthesis equation.

• To demonstrate how animals convert glucose and oxygen into carbon dioxide and water using sunlight as energy.

• To show the process by which plants convert carbon dioxide and water into glucose and oxygen using sunlight as energy.

• To illustrate the process of how plants absorb water and release carbon dioxide using sunlight as energy.

• To depict the process of how plants convert oxygen and water into carbon dioxide and glucose using sunlight as energy.

Why is photosynthesis important for the environment?

• It depletes the ozone layer

• It causes air pollution

• It produces oxygen and removes carbon dioxide from the atmosphere.

• It has no impact on the environment

How does photosynthesis benefit living organisms?

• It depletes the oxygen in the atmosphere

• It releases harmful toxins into the environment

• It causes global warming

• It provides oxygen and food (glucose) for energy.
