Photosynthesis

What is the balanced symbol equation for photosynthesis?

Which of the following are the raw materials of photosynthesis?

• Oxygen and water

• Glucose and carbon dioxide

• Carbon dioxide and water

• Oxygen and glucose

What are the products of photosynthesis?

• Oxygen and glucose

• Water and carbon dioxide

• Glucose and carbon dioxide

• Water and oxygen

Why is sunlight essential for photosynthesis?

• It heats up the plant to make reactions faster.

• It provides the energy needed to produce glucose.

• It makes the plant absorb more carbon dioxide.

• It helps oxygen get into the plant.

What is a limiting factor in photosynthesis?

• A factor that speeds up photosynthesis.

• A factor that decreases the rate of photosynthesis when it is in short supply.

• A factor that helps the plant store glucose.

• A factor that converts sunlight into chemical energy.

How does temperature affect photosynthesis?

• Higher temperatures always increase the rate of photosynthesis.

• Extremely high or low temperatures can slow down or stop photosynthesis.

• Temperature has no effect on photosynthesis.

• Only low temperatures increase photosynthesis.

Why do plants need glucose?

• For energy to carry out their life processes and for growth.

• To make oxygen for the environment.

• To store carbon dioxide.

• To make the plant’s leaves green.

How can you determine a limiting factor from a graph?

• By looking for a point where increasing one factor no longer increases the rate of photosynthesis.

• By comparing the color of the graph.

• By finding the point where all factors are the same.

• By calculating the amount of glucose produced.

What role do chloroplasts play in photosynthesis?

• They store glucose and nutrients.

• They absorb sunlight and convert it into energy for photosynthesis.

• They transport oxygen from the leaves to the roots.

• They store carbon dioxide for future use.

How does carbon dioxide concentration impact photosynthesis?

• Increased carbon dioxide always decreases the rate of photosynthesis.

• Increased carbon dioxide increases the rate of photosynthesis until a certain point.

• Carbon dioxide does not affect the rate of photosynthesis.

• Decreasing carbon dioxide increases the rate of photosynthesis.
