  1. 1The cell theory states that
    1. Aall living things are composed of cells
    2. Bcells are small units of living organisms
    3. Cnew cells come from pre-existing cells by cell division
    4. Dall of the above
    5. Ea and b only
  2. 2When using microscopes, the resolution refers to
    1. Athe ratio between the size of the image produced by the microscope and the actual size of the object
    2. Bthe degree to which a particular structure looks different from other structures around it.
    3. Chow well a structure takes up certain dyes.
    4. Dthe ability to observe two adjacent objects as being distinct from each other.
    5. Ethe degree to which the image is magnified.
  3. 3A spherical cell has a radius of 34 micrometers. What is its surface area/volume ratio?
    1. A0.088
    2. B0.12
    3. C11.3
    4. D55.7
    5. E127
  4. 4If a motor protein was held in place and a cytoskeletal filament was free to move, what type of motion would occur when the motor protein was active?
    1. AThe motor protein would "walk" along the filament.
    2. BThe filament would move.
    3. CThe filament would bend.
    4. DAll of the above would happen.
    5. EOnly b and c would happen.
  5. 5Each of the following is part of the endomembrane system except
    1. Athe nuclear envelope
    2. Bthe endoplasmic reticulum
    3. Cthe Golgi apparatus
    4. Dlysosomes
    5. Emitochondria
  6. 6Vesicle transport occurs between the ER and the Golgi in both directions. Let's suppose a researcher added a drug to cells that inhibited vesicle transport from the Golgi to the ER but did not affect the vehicle transport from the ER to the Golgi. If you observed cells microscopically after the new drug was added, what would you expect to see happen over the course of 1 hour?
    1. AThe ER would get smaller, and the Golgi would get larger.
    2. BThe ER would get larger, and the Golgi would get smaller.
    3. CThe ER and the Golgi would stay the same.
    4. DBoth would get larger.
    5. EBoth would get smaller.
  7. 7Functions of the smooth endoplasmic reticulum include
    1. Adetoxification of harmful organic molecules
    2. Bmetabolism of carbohydrates
    3. Cprotein sorting
    4. Dall of the above
    5. Ea and b only
  8. 8The central vacuole in many plant cells is important for
    1. AStorage
    2. BPhotosynthesis
    3. CStructural Support
    4. Dall of the above
    5. Ea and c only
  9. 9Let's suppose an abnormal protein contains three targeting sequences: an ER signal sequence, an ER retention sequence, and a mitochondrial matrix-targeting sequence. The ER retention sequence is supposed to keep proteins within the ER. Where would you expect this abnormal protein to go? Note: Think carefully about the timing of events in protein sorting and which events occur cotranslationally and which occur post-translationally.
    1. AIt would go to the ER
    2. BIt would go to the mitochondria
    3. CIt would go both to the ER and mitochondria equally.
    4. DIt would remain in the cytosol
    5. EIt would be secreted
  10. 10Which of the following observations would NOT be considered evidence for the endosymbiosis theory?
    1. AMitochondria and chloroplasts have genomes that resemble smaller versions of bacterial genomes
    2. BMitochondria, chloroplasts, and bacteria all divide by binary fission.
    3. CMitochondria, chloroplasts, and bacteria all have ribosomes.
    4. DMitochondria, chloroplasts, and bacteria all have similar sizes and shapes.
    5. EAll of the above are considered evidence for the theory.
