1,000 Cell: Smallest Unit of Life Cancer Cells SEM 2,000 complex vs simple http://www.cellsalive.com/howbig.htm How Life is Organized Prokaryotic Cell Plan Eukaryotic Cell Plan Comparison of Cell Types Prokaryotic cell Colorized TEM 15,000 Nucleoid region Nucleus Eukaryotic cell Note - Size, scale, internal organization of each Organelles Scale of Life Cells are limited in size because of surface area to volume ratio Prokaryotic Cell Structure Lacking well defined nuclei or organelles Variety of shapes and sizes Variety of Shapes and Sizes Prokaryotic Pneumonia Strep Throat Lyme’s Disease Botchulism Compartmentalization of Eukaryotic Cells Many small enclosed environments to create environments for unique chemical reactions. Note the continuous flow of membranous compartments Endomembrane system- internal system of membrane bound compartments Animal Cell Plant Cell
