• All living things are composed of cells.

• Living cells come only from other living cells.

• Each cell contains a cell membrane, cytoplasm, nucleus, mitochondria, and endoplasmic reticulum.

• Cells are the smallest structure of living things that can perform the functions necessary for life.

This early cell theory scientist looked in a microscope and discovered "animalcules" in the gunk from his teeth and pond water.
