CELLS: are the smallest biological unit able to sustain life Organisms can be broken down into two general classifications: prokaryotes and eukaryotes. A primary difference is cell type. Prokaryotes have cells with no “true” nucleus i.e. the nuclear material is not bound by a membrane and they have no organelles (areas within a cell performing a specific function bound by a membrane). Bacteria are examples of prokaryotes. Eukaryotes have a nucleus and organelles. DO: View the mixed protozoan slide under scanning and low powers. Note that these simple one celled organisms have a defined nucleus and many organelles. They belong to the Kingdom Protista. A chloroplast, a membrane bound unit within a plant cell where photosynthesis takes place, is an example of an organelle.
