Photosynthesis and Energy Flow Quiz

Arjun and Hannah are learning about how plants make their own food. Which two statements correctly describe the process of photosynthesis?

• Animals use photosynthesis to create food from sunlight

• Photosynthesis can occur without sunlight during the night

• Plants convert carbon dioxide and water into glucose and oxygen

• Photosynthesis primarily occurs in the chloroplasts of plant cells

Max has a group of goldfish in his tank at home. He notices that they are not as active as usual. Max wants to boost their energy levels by enhancing their cellular respiration. Which of the following actions would most likely enhance the cellular respiration rate in the goldfish?

• decreasing the water temperature in the tank

• increasing the amount of oxygen in the tank

• adding more plants to the tank

• reducing the amount of food given to the fish

Hannah is studying photosynthesis in her biology class. Which statement correctly describes the process she is learning about?

• The process in which oxygen is used requires light energy.

• The process in which glucose is produced requires oxygen.

• The process in which carbon dioxide is used releases light energy.

• The process in which carbon dioxide is used also forms glucose.

Ethan is learning about photosynthesis in his science class. Why is sunlight so important to this process?

• It turns the oxygen into carbon dioxide to be released through the leaves.

• It provides the needed temperatures to change glucose into water.

• It provides the energy needed to combine the atoms in glucose.

• It raises the levels of gases in the air so that water can change into oxygen.

Sophia and Ethan are learning about how organisms get the energy they need. How do they explain this process?

• Plants get energy from fertilizers, and animals get energy by drinking water.

• Plants get energy from glucose produced in the soil, and animals get energy directly from sunlight.

• Plants do not require energy because they do not move, and animals get energy by performing exercises.

• Plants break down the glucose they produce in photosynthesis, and animals get energy from eating other organisms.

Alma is preparing for the upcoming track season by incorporating running into her routine. After consuming a granola bar, she embarks on a series of laps around the track. How does her body process the food to provide energy during her exercise? Arrange the following events in sequence as they occur in her body’s cells while she runs.

• A glucose molecule is absorbed into the bloodstream.

• The glucose molecule is transported into a body cell.

• The glucose molecule undergoes glycolysis in the cytoplasm.

• Pyruvate molecules enter the mitochondria.

• Energy is produced through the Krebs cycle and electron transport chain.
