T1.1.3 Plant and animal cells compared Quiz: KS3 Biology, Unit 1

The 20 questions

1. Which feature do plant cells have that animal cells do not?

   • Mitochondria that release energy by aerobic respiration in the cell
   • A rigid cell wall made of cellulose
   • A nucleus that holds the genetic material and controls the cell
   • A cell membrane that controls the movement of substances in and out

2. Which structure is found in both plant and animal cells and releases energy from glucose?

   • Mitochondria
   • Chloroplasts
   • A large permanent vacuole
   • A cell wall

3. Animal cells usually have which kind of vacuole compared with plant cells?

   • No vacuoles at all
   • A vacuole that fills most of the cell
   • Small, temporary vacuoles
   • A large permanent vacuole

4. A cell has a rigid outer layer, green structures and a large central sac. What type of cell is it most likely to be?

   • A nerve cell from an animal
   • A plant cell
   • A bacterium with no nucleus
   • An animal cell

5. A student compares a cheek cell with an onion cell. Which difference should they expect to see?

   • The cheek cell has a cell wall, but the onion cell does not
   • Neither cell has a nucleus
   • The onion cell has a cell wall, but the cheek cell does not
   • Both cells have chloroplasts

6. Which statement describes the typical shape of plant and animal cells?

   • Plant cells tend to be box-like, while animal cells are often irregular
   • Plant and animal cells always have identical shapes and sizes under a microscope
   • Animal cells are always box-like, while plant cells are always round and smooth
   • Animal cells are always much larger than plant cells of the same type

7. Why do plant cells keep a fixed shape even when full of water?

   • The chloroplasts hold the cell wall in shape by pulling it inwards
   • The mitochondria pump water out of the cell to keep its shape fixed
   • The vacuole presses outward against the cell wall
   • The nucleus shrinks inside the cell to make the cell firm and rigid

8. Which structure is found in plant cells but not in animal cells?

   • A cell wall, made of cellulose, which supports the cell
   • A mitochondrion, where aerobic respiration takes place
   • A cell membrane, which controls what enters and leaves
   • A nucleus, which controls the activities of the cell

9. Which statement about animal cells is correct?

   • Animal cells have chloroplasts but no nucleus to control their activities
   • Animal cells have a cell wall but no cell membrane to hold them together
   • Animal cells have a cell wall and a cell membrane, like plant cells do
   • Animal cells have a cell membrane but no cell wall

10. Two cells of the same size, one plant and one animal, are compared. Which cell has more room for storing water?

    • Both cells have exactly the same space available for storing water inside them
    • The plant cell, because it has a large vacuole
    • The animal cell, because it has chloroplasts that store water for later use
    • The animal cell, because it has a cell wall that stores extra water inside it

11. A student says all plant cells are green. What is the best response?

    • Not all plant cells are green, because root cells have no chloroplasts
    • All plant cells are green because they all contain chloroplasts that give them colour
    • Plant cells are green only when they have a nucleus and a large vacuole
    • Animal cells are green because they contain chloroplasts that absorb sunlight

12. Which feature of animal cells allows them to change shape more easily?

    • Having no rigid cell wall
    • Having a large central vacuole
    • Having a thick cellulose wall
    • Having many chloroplasts

13. Which structure is found in both plant and animal cells and controls what the cell does?

    • The chloroplast
    • The nucleus
    • The large vacuole
    • The cell wall

14. Which cell would be most likely to have a large central vacuole?

    • An animal muscle cell that contracts to move bones and joints of the body
    • A red blood cell that carries oxygen around the body in the blood
    • A nerve cell that carries electrical signals along a long thin path
    • A plant cell storing water

15. A cell has a large vacuole, a cell wall and chloroplasts. Which group is it most likely to come from?

    • Plants
    • Animals
    • Insects
    • Humans

16. Why is it useful to compare plant and animal cells when learning biology?

    • Plant cells have no organelles at all, which makes them very different
    • They share many parts but have some different ones that match their roles
    • They are identical in every respect, so the comparison tells us nothing new
    • Animal cells are always bigger than plant cells, so they can be told apart easily

17. Which is a good reason to use a light microscope to compare plant and animal cells?

    • It shows the atoms that make up each cell in very fine detail
    • It shows the DNA double helix clearly so the shape of the molecule is visible
    • It shows cell walls, chloroplasts and nuclei clearly enough to compare
    • It shows the cell membrane in full molecular detail and its exact structure

18. Which part would you look for first to tell a plant cell from an animal cell under a light microscope?

    • The nucleus
    • The cytoplasm
    • The cell wall
    • The cell membrane

19. Which statement about the nucleus in plant and animal cells is correct?

    • Only animal cells have a nucleus, which is missing from plant cells entirely
    • The nucleus is found only in bacteria and not in plant or animal cells
    • Both plant and animal cells have a nucleus that controls the cell
    • Plant cells have a nucleus but animal cells do not have one at all

20. Which cell part is found in a plant leaf cell but not in a human skin cell?

    • Nucleus
    • Cell membrane
    • Cytoplasm
    • Chloroplast
