Students use craft supplies and household items to create a simple model of a cell. It is a small, watery, compartment filled with chemicals and a complete copy of the organism's genome. Bacteria are different from most other cells because they have fewer organelles than most other cells. In fact, scientists think that some organelles, like the mitochondria, may have been created when a bacteria made its home inside of a larger cell. Lipid moleculeS are the basic building blocks that are made of things like oil or fat.
Proteins are also little machines that do work inside the cell and inside the organelles.
The cell's DNA contains the instructions for making all of the proteins used in the cell. Enzymes are little machines inside the cell which do things like building new moleucules, breaking apart old molecule, and many other jobs.
