About This Quiz
Unit 2 - Cell Structures Test - Quiz

This quiz tests knowledge on cell structures, including the nature of viruses, commonalities between cell types, and the role of vaccines.

2.
We’ll put your name on your report, certificate, and leaderboard.
2. Plant cells have a large membrane-bound compartment in which water, waste products, and nutrients can be stored. This compartment is called the

Explanation

Vacuoles are storage areas in plant cells. They store mostly water. Plants will have 1 large central vacuole. Animal cells will either have several small vacuoles or none.

Submit
3. What can a vaccine do when it is injected into the body?

Explanation

Vaccines introduce a weakened or inactive virus into an organism. The organism then produces antibodies to that virus, which make the organism immune to future infections.

Submit
4. Which of the following structures serves as the cell's boundary from its environment?

Explanation

The cell membrane forms a boundary between the cytoplasm and the outer environment.

Submit
5. Which of the following is a function of the cell membrane?

Explanation

The cell membrane acts like a gate-keeper, receptionist, or security guard because it regulates (controls) which materials can come in or go out of the cell.

Submit
6. Which of the following is NOT true about endoplasmic reticulum?

Explanation

Smooth ER makes lipids & does not contain ribosomes. It is not involved in protein production/modification.

Submit
7. Which of the following is NOT a function of the nucleus?

Explanation

The nucleus contains the instructions for making proteins (DNA) but it does not make the proteins. That is what the ribosome does.

Submit
8. Eukaryotes usually contain

Explanation

Eukaryotes have a nucleus with DNA and membrane-bound organelles.

Submit
9. Which of the following structures allows for the movement of organelles within the cell as well as movement of the cell itself?

Explanation

The cytoskeleton is responsible for movement and maintaining cell shape.

Submit
10. Which of the following is TRUE of viruses?

Explanation

Viruses evolve, reproduce, and have a genetic code (DNA or RNA).
They do NOT meet the other characteristics of life.

Submit
11. Which organelle contains digestive enzymes used to break down large compounds into small particles that the cell can use?

Explanation

Lysosome contains digestive enzymes that break down large molecules, invading bacteria, and damaged organelles. It acts like a janitor.

Submit
12. Which of the following are never found in animal cells?

Explanation

Chloroplasts are only found in plant cells, NEVER in animal cells.

Submit
13. What is the correct order of organization of all living things from simplest to most complex?

Explanation

organelles (cell structures) are the smallest & make up cells. Organisms are the largest.

Submit
14. Prokaryotes are single-celled organisms that do not have

Explanation

Prokaryotes do not have a nucleus or membrane-bound organelles.

Submit
15. The genetic material that provides instructions for making proteins is

Explanation

DNA is the instructions for making proteins.
Ribosomes make proteins.
Cytoplasm and cytosol are the same thing = cell jelly (not directly involved in making proteins)

Submit
16. Which of the following organelles makes food molecules for the cell through the process of photosynthesis?

Explanation

Chloroplasts make food (glucose) for plant cells.

Submit
17. The organelle that modifies, sorts, and packages proteins is the

Explanation

The Golgi apparatus is responsible for sorting & packaging proteins to be exported from the cell.

Submit
18. Which of the following contains a nucleus?

Explanation

Eukaryotes have a nucleus. Prokaryotes do NOT have a nucleus.

Submit
19. Which cells have a cell membrane, cytoplasm, ribosomes, and DNA?

Explanation

Both prokaryotes and eukaryotes (all cells) contain cell membrane, cytoplasm, ribosomes, & DNA.

Submit
20. A cell that requires a lot of energy might contain large numbers of

Explanation

Mitochondria produce energy SO cells that need a lot of energy will need more mitochondria.

Submit
21. All the following are found in both plant and animal cells, except ___.

Explanation

Animal cells do not have a cell wall but plant cells do.

Submit
22. The organelle that modifies proteins before they are sent to the Golgi apparatus is the

Explanation

After the protein is made by the ribosome, the Rough ER modifies the proteins and then sends them to the Golgi to be packaged and exported.

Submit
23. After learning about viruses in Biology class, Sam decides to have his cat vaccinated against feline leukemia virus. According to cell theory, are viruses, such as feline leukemia, considered living things? Type question here

Explanation

Viruses are not cells and so they are not considered living. They do evolve, reproduce, & contain DNA.

Submit
24. Which of the following do prokaryotes, eukaryotes, and viruses all have in common?

Explanation

Viruses are not cells and so they are not considered living. They do evolve, reproduce, & contain DNA.

Submit
25. Which of the following are rarely found in plant cells?

Explanation

Lysosomes are found in animal cells but are usually NOT found in plant cells. Both plant and animal cells contain a cell membrane and mitochodria. Plants usually have 1 large vacuole.

Submit
26. An organelle found in a liver cell would best be identified as a smooth endoplasmic reticulum if its primary function was which of the following? (HINT: What is the function of the smooth ER?)

Explanation

Smooth ER is responsible for detox and making lipids to repair the cell membrane (like the school nurse)

Submit
27. What is the basic structure of a virus?

Explanation

Viruses do not have "tails." Viruses are not cells. A capsid is the same thing as a protein coat.
Viruses are made of 2 things: nucleic acids (DNA/RNA) on the inside & protein on the outside

Submit
28. Viruses cause disease by

Explanation

Viruses force cells to reproduce the virus. Viruses can not make anything themselves. They must have a host.

Submit
29. What do prokaryotes and eukaryotes have in common?

Explanation

All cells contain the following: cell membrane, cytoplasm, ribosomes, DNA & RNA
Prokaryotes do NOT have a nucleus or membrane-bound organelles like chloroplasts & mitochondria.

Submit
30. Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use for energy?

Explanation

Mitochondria make energy for the cell.

Submit
31. All cells contain which of the following?

Explanation

All cells (prokaryotes & eukaryotes) will have a cell membrane, cytoplasm, ribosomes, & DNA/RNA.

Submit
32. The presence of which structure indicates that cells are NOT bacteria?

Explanation

Bacteria (prokaryotes) will have a cell wall, cell membrane, cytoplasm, ribosomes, & DNA/RNA.
Prokaryotes do not have a nucleus or membrane-bound organelles like chloroplasts.

Submit
33. Naomi adds a chemical called cyclohexamide to cells grown in a test tube. Within minutes, she identifies short incomplete segments of proteins in the cells. On which organelle does cyclohexamide act?

Explanation

If the chemical disrupts the proteins from being made, it must act on the organelle that makes proteins. Ribosomes make proteins.

Submit
34. Which of the following is the function of the nucleolus?

Explanation

The nucleolus makes ribosomes. The nucleus control's the cell. The cell membrane contains cytosol. The ribosomes make proteins.
