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.
A diagram representing the relationship between photosynthesis and cellular respiration is shown below. The numbered boxes in the diagram represent which of the following?
1 - water; 2 - nitrogen
1 - nitrogen; 2 - oxygen
1 - oxygen; 2 - carbon dioxide
1 - carbon dioxide; 2 – water
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.
Which gas is removed from the atmosphere during photosynthesis?
hydrogen
oxygen
nitrogen
carbon dioxide
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
Which of the following are the reactants of photosynthesis?
water and glucose
glucose and carbon dioxide
carbon dioxide and water
oxygen and water
If a plant died from lack of food, which structure is most likely missing or damaged?
flower
root
stem
leaves
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?
Only species Y is aerobic.
Only species Y is anaerobic.
Both species X and Y are aerobic.
Both species X and Y are anaerobic.
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP
Which of the following structure is where cellular respiration occurs in the cell?
nucleus
cytoplasm
mitochondria
vacuoles
What function does ATP carry out in living things?
aids in protein folding and coiling
used to capture and transfer energy
identifies DNA start sequences for transcription
helps maintain the fluidity of cell membranes
Terrestrial plants have stomata on the surface of their leaves. A single stomata is 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.
Plant cells that are specialized for cell division are most likely found in what part of the plant?
root tips
leaf epidermis
stem epidermis
vascular tissue
If the xylem in a young tree is damaged, which process is first affected?
performing photosynthesis
transporting sugar to the roots
transporting water to the leaves
absorbing water from the soil
A plant species lives in an area with limited sunlight. Which physiological adaptation would be most useful to the plant?
colorful flowers
large leaves
deep roots
thin cuticle
