How Life is Organized
Eukaryotic Cell Plan
Prokaryotic Cell Plan
5
Comparison of Cell Types
Note - Size, scale, internal organization of each

Scale of Life
Cells are limited in size because of surface area
to volume ratio
7
Prokaryotic Cell Structure

• Lacking well defined nuclei or organelles
• Variety of shapes and sizes

Variety of Shapes and Sizes Prokaryotic
Pneumonia
Strep Throat

• Lymes Disease

Botchulism
9
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
