CELL PART ANALOGIES

Parts of a Cell

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.

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

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.

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.

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.

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.

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

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

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.

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

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

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.

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