This one cell contained all the instructions necessary to make you. It divided many times to produce the millions and millions of cells in your body.

Animal cells have softer membranes than plants cells.
Like plant cells, they contain a series of tubes called the endoplasmic reticulum where important cell chemicals called enzymes are made. Unlike plant cells, they have a lysosome for waste disposal.
