                            (YOO-kare-ee-AW-tick) A cell that has a nucleus and other organelles not found in prokaryotes; includes all animal and most plant cells.
                                                            
                                                     
                        
                                                
                        
                        
                            A cell that has a true nucleus surrounded by a membrane. This group includes all animal and plant cells, except cyanobacteria.
                                                            
                                                     
                        
                                                
                        
                        
                            A cell that contains a nucleus. Humans and all higher organisms have eukaryotic cells. Bacteria and other primitive organisms have prokaryotic cells, whose chromosome(s) are not segregated from the rest of the cellular material in a nucleus.
                                                            
                                                     
                        
                                                
                        
                        
                            A cell containing a nucleus that is bound within a thin membrane and contains almost all of the cell's DNA. Eukaryotic cells have internal specializations, and this allows different cells to specialize in a multicellular organism. Most familiar living things—your pets, your plants, you—are eukaryotes.
