Photosynthesis Quiz

What is the role of chlorophyll in photosynthesis?

• Produces oxygen for photosynthesis

• Regulates temperature for photosynthesis

• Provides water for photosynthesis

• Absorbs light energy for photosynthesis

Name one factor that affects the rate of photosynthesis.

• Wind speed

• Soil pH

• Light intensity, temperature, or carbon dioxide concentration

• Humidity

Why is photosynthesis important for plants?

• Photosynthesis only provides plants with water, not energy

• Plants get energy from other sources, so photosynthesis is unnecessary

• Photosynthesis is not important for plants

• Photosynthesis provides plants with the energy they need to grow and survive.

What is the main pigment responsible for capturing light energy during photosynthesis?

• Carotene

• Hemoglobin

• Chlorophyll

• Melanin

How does the availability of water affect photosynthesis?

• Photosynthesis stops completely when there is too much water

• Photosynthesis occurs faster when there is less water available

• Water availability affects the rate of photosynthesis.

• Water availability has no impact on photosynthesis

What are the products of photosynthesis?

• Methane and sulfur dioxide

• Glucose and oxygen

• Nitrogen and hydrogen

• Carbon dioxide and water

What are the two main stages of photosynthesis?

• Chlorophyll reaction and Calvin cycle

• Light absorption and Calvin cycle

• Dark reaction and Calvin cycle

• Light reaction and Calvin cycle

How does temperature affect the rate of photosynthesis?

• By affecting the amount of water available to the plant

• By changing the color of the light absorbed by the plant

• By altering the genetic makeup of the plant

• By influencing the activity of enzymes involved in the process.

Explain the process of photosynthesis in simple terms.

• Plants use wind to make food

• Plants use sunlight to make food

• Plants use water to make food

• Plants use moonlight to make food

What is the role of carbon dioxide in photosynthesis?

• It has no role in photosynthesis

• It is used by plants to produce glucose and oxygen.

• It is used by plants to produce carbon monoxide

• It inhibits the process of photosynthesis
