CQA2 Review: Photosynthesis, Cellular Respiration, and ATP

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.Which statement describes how photosynthesis and cellular respiration are interrelated?

•  Oxygen is produced during cellular respiration and stored during photosynthesis.
• Carbon dioxide and water released by cellular respiration are used in photosynthesis.
• Photosynthesis releases the energy that is stored during the process of cellular respiration.
•  Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

Which of the following is the correct equation for PHOTOSYNTHESIS?

• Light and 6CO₂ + 6H₂0 --> C₆H₁₂O₆ + 6O₂

• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> 6O₂ + light

Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period.
Which of the following statements best explains Mike’s observations?

• Cells decompose most quickly under the most intense light.
• Water evaporates from plants faster under the most intense light.
• Photosynthesis occurs at the highest rate under the most intense light.
• Gases in the leaves of plants expand most under the most intense light

Jake conducted an experiment with four bean plants. They were placed next to one another on a sunny windowsill. He gave each plant equal amounts of a different type of water. The plants were given tap water, distilled water, flavored water, or carbonated water. He made the following observations after three weeks. Based on his results, Jake concluded that tap water is not good for plants. How can Jake change his experimental design to improve the validity of his results?

• carry out multiple trials, and increase the number of plants that are given each type of water

• establish a control group that includes different types of plants

• establish another dependent variable to generate more data

• carry out multiple trials that include fewer plants, and increase the types of water given to the plants

Terrestrial plants have stomata on the surface of their leaves. Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants?

• Water enters the plant through the surface of the leaf for transpiration

• Gases for photosynthesis are exchanged through the surface of the leaf.

• Energy for cellular reproduction is absorbed through the surface of the leaf.

• Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction.
