Cell: Smallest Unit of Life
Boundary of life! Ect? Icf? Cell Membrane. If we Understand Cell function…we understand everything.
Cancer Cells

3. SEM 2,000
complex vs simple

4. How Life is Organized Eukaryotic Cell Plan Prokaryotic Cell Plan
This slide show how the prokaryotes are organized. But what unites the group? What divides the
Eukaryotic Cell Plan
Prokaryotic Cell Plan

5. Note - Size, scale, internal organization of each
Comparison of Cell Types
Prokaryotic cell
Nucleoid region
Nucleus
Eukar yotic cell
Organelles
Colorized TEM 15,000 
Note - Size, scale, internal organization of each

6. Cells are limited in size because of surface area to volume ratio
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

8. Variety of Shapes and Sizes Prokaryotic
Pneumonia
Strep Throat
Lyme’s 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
