  1. CELL PART ANALOGIES

  2. Parts of a Cell

  3. Cell Membrane • The cell membrane controls what goes in and out of the cell. • The cell membrane is like a screen door, because a screen door holds things out but lets air in.

  4. Cytoplasm • The cytoplasm holds cell parts in place. • The cytoplasm is like nails or glue because it holds things together.

  5. Nucleus • The nucleus controls all of the cells activities. • A nucleus is like a tour guide because they control all of the places people go on tours.

  6. Lysosome • A lysosome digests and recycles materials. • A lysosome is like an engine because an engine recycles oil. • It is the cell’s garbage disposal.

  7. Endoplasmic Reticulum • The endoplasmic reticulum is like a road way in the cell. • The endoplasmic reticulum is like a freeway, because it gets people from place to place.

  8. Golgi Apparatus • The Golgi apparatus assembles, packages and delivers. • The Golgi apparatus is like a post office, because the whole point of a post office is to package and deliver things.

  9. Chromosome • A chromosome stores information. • A chromosome is like a flash drive or a book because they store information.

  10. Centriole • A centriole helps organize the cell when it is divided. • A centriole is like a secretary because they organize things.

  11. Cytoskeleton • The cytoskeleton holds the shape of the cell. • The cytoskeleton is like the beams of a house because they help the house hold it’s shape.

  12. Mitochondria • The mitochondria burns food for energy • The mitochondria is like a fire because fires burn wood for energy.

  13. Vacuole • The vacuole is used for storage (mostly for water). • The vacuole is like a cupboard because you store things in it.

  14. Chloroplast • The chloroplast turns energy from the sun into energy the cell can use. • A chloroplast is like a solar panel because it uses the sun’s energy for other things.

  15. Cell Wall • The cell wall surrounds the plant cell and protects it. • It is made of a hard non-living substance called CELLULOSE.
