Questions with solutions
Q1 — Plant vs Animal Cells · medium · theory
A structure present in plant cells but absent in animal cells is the:
A. nucleus
B. cell wall ✓ Correct
C. cell membrane
D. mitochondrion
Solution: Plant cells have a rigid cell wall outside the membrane; animal cells do not.
Q2 — Plant vs Animal Cells · medium · theory
The plant cell wall is made mainly of:
A. chitin
B. fat
C. cellulose ✓ Correct
D. protein
Solution: The plant cell wall is composed mainly of cellulose, giving the cell rigidity.
Q3 — Plant vs Animal Cells · hard · theory
Chloroplasts are found in:
A. animal cells only
B. neither
C. plant cells only ✓ Correct
D. both plant and animal cells
Solution: Only plant (and some protist) cells contain chloroplasts for photosynthesis.
Q4 — Plant vs Animal Cells · medium · theory
A large central vacuole is a typical feature of:
A. red blood cells
B. animal cells
C. bacterial cells only
D. plant cells ✓ Correct
Solution: Mature plant cells usually have one large central vacuole; animal cells have small or no vacuoles.
Q5 — Plant vs Animal Cells · hard · theory
Which cell would you expect to have a fixed, rectangular shape?
A. An amoeba
B. An animal cell
C. A white blood cell
D. A plant cell (because of its cell wall) ✓ Correct
Solution: The rigid cell wall gives plant cells a fixed, often rectangular shape.
Q6 — Plant vs Animal Cells · medium · theory
Which of the following is found in animal cells but usually absent in higher plant cells?
A. Nucleus
B. Centrosome (centrioles) ✓ Correct
C. Cell membrane
D. Cytoplasm
Solution: Centrioles (centrosome) are typically present in animal cells and absent in most plant cells.
Q7 — Plant vs Animal Cells · easy · theory
Which structure is present in a plant cell but NOT in an animal cell?
A. Cell wall ✓ Correct
B. Cell membrane
C. Mitochondria
D. Nucleus
Solution: Plant cells have a rigid cellulose cell wall outside the membrane; animal cells have only a cell membrane. The nucleus, membrane and mitochondria are found in both.
Q8 — Plant vs Animal Cells · medium · theory
A student views two cells. Cell X has a large central vacuole, a cell wall and chloroplasts. Cell Y has many small vacuoles, no cell wall and a centriole. Which conclusion is correct?
A. X is an animal cell and Y is a plant cell
B. X is a plant cell and Y is an animal cell ✓ Correct
C. Both X and Y are animal cells
D. Both X and Y are plant cells
Solution: A large central vacuole, a cell wall and chloroplasts are typical plant features, so X is a plant cell. Small vacuoles, no cell wall and a centriole are animal features, so Y is an animal cell.
Q9 — Plant vs Animal Cells · hard · theory
When placed in pure water, an animal cell may swell and burst, but a plant cell in the same water swells only slightly and does not burst. The best explanation is that the plant cell:
A. Actively pumps the water back out through its vacuole
B. Has no cell membrane
C. Has a rigid cell wall that resists further expansion once the cell is turgid ✓ Correct
D. Does not let any water enter it
Solution: Water enters both cells by osmosis, but the rigid cell wall of the plant cell pushes back once the cell is turgid, preventing bursting. The animal cell has no wall, so it keeps swelling and eventually lyses.
Q10 — Plant vs Animal Cells · medium · theory
A typical plant cell stores extra carbohydrate as starch. In an animal cell the corresponding storage carbohydrate is:
A. Chitin
B. Sucrose
C. Cellulose
D. Glycogen ✓ Correct
Solution: Animal cells store carbohydrate as glycogen, whereas plant cells store it as starch. Cellulose is a structural wall material, not a storage form.
