Cell Quiz
Questions: 16 · 10 minutes
1. Where is most of a prokaryotic cell's DNA located?
Inside mitochondria
Inside a membrane-bound nucleus
Within the Golgi apparatus
In the nucleoid region
2. A eukaryotic cell is making a protein that will be released outside the cell. Which route best represents its movement?
Golgi apparatus → nucleus → lysosome → membrane
Ribosome on rough ER → Golgi apparatus → transport vesicle → plasma membrane
Smooth endoplasmic reticulum → mitochondrion → membrane
Nucleus → chloroplast → central vacuole → plasma membrane
3. A pancreatic cell produces and exports large quantities of digestive enzymes. Which structure would likely be especially abundant?
Smooth endoplasmic reticulum
Central vacuoles
Chloroplasts
Rough endoplasmic reticulum
4. Which set of features is normally found in both bacterial cells and animal cells?
A plasma membrane, cytoplasm, DNA, and ribosomes
A nucleus, cytoplasm, DNA, and ribosomes
A cell wall, mitochondria, DNA, and ribosomes
Chloroplasts, cytoplasm, DNA, and a plasma membrane
5. A muscle cell has a persistently high demand for aerobic energy. Which adaptation would most directly help meet that demand?
Removing most ribosomes
Developing a cellulose cell wall
Having numerous mitochondria
Expanding the nucleoid region
6. Which structure forms a selective boundary around every living cell?
Cell wall
Plasma membrane
Nuclear envelope
Protein capsule
7. Which comparison between typical prokaryotic and eukaryotic cell division is accurate?
Prokaryotes commonly divide by binary fission, while eukaryotic body cells commonly divide by mitosis
Prokaryotes use meiosis, while eukaryotes use binary fission
Both normally divide only through mitosis
Prokaryotes divide inside a nucleus, while eukaryotes divide without organizing chromosomes
8. What is the primary function of ribosomes?
Storing genetic information
Breaking down worn cellular material
Assembling proteins from amino acids
Regulating movement across the cell boundary
9. Which organelle produces most of a eukaryotic cell's ATP during aerobic cellular respiration?
Golgi apparatus
Mitochondrion
Lysosome
Nucleus
10. An animal cell is placed in a solution with a much higher solute concentration than its cytoplasm. What is the most likely immediate result?
Solute leaves the cell, causing it to swell
Water enters the cell, causing it to burst
The cell wall prevents any change in volume
Water leaves the cell, causing it to shrink
11. A cell seen under a microscope has chloroplasts, a large central vacuole, and a cellulose cell wall. What type of cell is it?
An archaeal cell
An animal cell
A bacterial cell
A plant cell
12. Which organelle contains digestive enzymes that break down macromolecules and worn cell components in many animal cells?
Nucleolus
Centrosome
Lysosome
Golgi apparatus
13. A cyanobacterium performs photosynthesis but is classified as a prokaryote. Which statement best explains how this is possible?
It uses photosynthetic membranes that are not chloroplasts
Its nucleus temporarily disappears while photosynthesis occurs
It relies on mitochondria to capture light energy
Every photosynthetic cell must contain chloroplasts, so it is actually eukaryotic
14. An antibiotic prevents peptidoglycan from being assembled. Which cellular structure is most directly affected?
The fungal cell membrane
The bacterial cell wall
The eukaryotic nuclear envelope
The plant cell's cellulose wall
15. A scientist observes a single-celled organism whose DNA is not enclosed by a membrane. How should the organism be classified?
A prokaryote
A unicellular eukaryote
A plant cell
A fungal cell
16. A cell's plasma membrane suddenly loses its selective permeability. What is the most direct likely consequence?
The cell immediately gains a second nucleus
Ribosomes stop reading messenger RNA because DNA disappears
Substances move in and out without normal regulation
The cell converts its membrane into a rigid cell wall
