Photosynthesis and Respiration Test Review

During a science class, William and Maya learned that plants benefit humans in a certain way. Avery, who missed the class, asked them to explain. They told Avery that plants benefit humans by -

• producing water during respiration.

• producing water during photosynthesis.

• producing oxygen during respiration.

• producing oxygen during photosynthesis.

Abigail, Oliver, and Noah are studying plants in their biology class. They are trying to understand the relationship between the process plants use to convert sunlight into food (photosynthesis) and the process cells use to break down food into energy (cellular respiration). Can you help them understand?

• Abigail thinks that the reactants of cellular respiration and photosynthesis are the same but their products are different.

• Oliver believes that cellular respiration is one of the steps in the process of photosynthesis.

• Noah suggests that photosynthesis is one of the steps in the process of cellular respiration.

• They all agree that the reactants of cellular respiration are the products of photosynthesis and the reactants of photosynthesis are the products of cellular respiration.

Daniel, Elijah, and Henry are studying for their biology exam. They are comparing diagrams of cellular respiration and photosynthesis. Daniel asks, 'How would a diagram of cellular respiration differ from a diagram of photosynthesis?'

• The cellular-respiration diagram would show electromagnetic waves as the final product.

• The cellular-respiration diagram would show glucose as the main source of energy.

• The cellular-respiration diagram would show energy stored in large protein molecules.

• The cellular-respiration diagram would show water as the main source of chemical energy.

Sophia, Anika, and Priya are studying for their biology exam. They are discussing the energy needs for photosynthesis and cellular respiration. Sophia says, 'Solar energy is needed for cellular respiration but not for photosynthesis.' Anika says, 'Chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.' Priya says, 'Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration.' But, their teacher corrects them and says, 'Which statement accurately describes the energy needs?'

• Solar energy is needed for cellular respiration but not for photosynthesis.

• Chemical energy in the form of glucose is needed for both cellular respiration and photosynthesis.

• Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration.

• Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.

Ethan, Aiden, and David were studying about photosynthesis and cellular respiration in their biology class. They learned that both processes involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes that they learned?

• Chemical energy → Mechanical energy

• Light energy → Chemical energy

• Chemical energy → Light energy

• Mechanical energy → Light energy

Abigail, Michael, and Maya are working on a science project about cellular respiration. They are discussing the primary function of the mitochondria in this process. Michael suggests it's the production of glucose, Maya thinks it's the absorption of sunlight, but Abigail believes it's the conversion of glucose into ATP. Who is correct?

• Production of glucose

• Absorption of sunlight

• Conversion of glucose into ATP

• Release of oxygen
