Name ______________________   Date ____________

  1. Which organelle is found only in plant cells and gives the cell a stiff, fixed shape?

    • Cell wall
    • Mitochondria
    • Ribosome

  2. Which part controls what goes in and out of a cell?

    • Nucleus, the control room
    • Cell membrane
    • Cytoplasm, the jelly fill

  3. The nucleus holds the instructions that control the whole cell.

    Circle one:   True   False

  4. A plant cell needs to make its own food using sunlight. Which organelle does this job?

    • Chloroplast
    • Nucleus, the control room
    • Cytoplasm, the jelly fill

  5. Which organelle breaks down food to release energy for the cell's activities?

    • Chloroplast, the food maker
    • Mitochondria
    • Vacuole, the water bag

  6. Animal cells have chloroplasts, just like plant cells.

    Circle one:   True   False

  7. A scientist sees a cell wall and chloroplasts in a cell but isn't sure what type of cell it is. What should she conclude?

    • It's an animal cell, because those parts appear in both plant and animal cells
    • She cannot tell, because both plant and animal cell types have those parts
    • It's a plant cell, because only plant cells have a cell wall and chloroplasts

  8. Sam says the vacuole makes proteins for the cell. What is wrong with this statement?

    • Ribosomes make proteins; vacuoles store substances
    • The vacuole is only in animal cells
    • The vacuole makes energy, not proteins

The Parts Inside a Cell W1-mt_bABr-c2DfV-s1

  1. Cell wall · The cell wall sits outside the membrane, and only plant cells have one.
  2. Cell membrane · The cell membrane is the thin skin that lets some things in and keeps others out.
  3. True · The nucleus works like a control room, storing the instructions the cell follows.
  4. Chloroplast · Chloroplasts trap sunlight and use it to make food for the plant cell.
  5. Mitochondria · Mitochondria release the energy a cell needs to carry out its work.
  6. False · Only plant cells have chloroplasts. Animal cells don't make their own food this way.
  7. It's a plant cell, because only plant cells have a cell wall and chloroplasts · The cell wall and chloroplasts only occur in plant cells, so this must be a plant cell.
  8. Ribosomes make proteins; vacuoles store substances · Vacuoles store substances, while ribosomes build proteins.
