Photosynthesis and Respiration

How are cellular respiration and photosynthesis related, in terms of energy?

• The energy captured in photosynthesis is used to power cellular respiration.

• The energy transformed in cellular respiration is used to power photosynthesis.

• Photosynthesis and respiration perform the same task in terms of energy transformation

• Energy is not involved in either photosynthesis or cellular respiration.

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.

• Cellular respiration produces oxygen, while photosynthesis uses oxygen.

• Photosynthesis releases energy, while cellular respiration stores energy.

• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

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.

Two test tubes were filled with a solution of bromthymol blue. A student exhaled through a straw into each tube, and the bromthymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?

• Oxygen was produced by photosynthesis.

• Carbon dioxide was removed by photosynthesis.

• Carbon dioxide was produced by respiration.

• Oxygen was removed by respiration.

A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?

• The plant will grow faster because it is sheltered from the wind.

• The plant will die because it does not have oxygen for photosynthesis

• The plant will die because it does not have carbon dioxide for photosynthesis

• The plant will grow at a slower rate because it requires more water.

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. He 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
