Introduction to the Cell Cell Theory, Prokaryotes and Eukaryotes

Cell Theory All organisms are made of one or more cells Cells are the basic units of structure and function of all organisms New cells are produced from existing cells when they divide

Prokaryotic Cells (prokaryotes) Simplest type of cell – found in bacteria Small size – between 1 – 10 microns Does not have a nucleus Does not have membrane bound organelles

Eukaryotic Cells (eukaryotes) Complex cell structure – found in protists, animals, plants and fungi Large size – between 10 – 100 microns Has a nucleus Has membrane bound organelles
