1. Prokaryote vs. Eukaryote
November 5, 2014

2. What is a Cell? Cell – Basic unit of living things.
Organisms are either:
Unicellular – made of one
cell such as bacteria and
amoebas. OR
Multicellular – made of
many cells such as plants
and animals.

3. Cell Theory
Confirmed discoveries that all scientists believe to be true about cells:
1. Cells are the basic unit of life.
2. All living things are made of cells.
3. New cells are produced from existing cells.

4. The Discovery of Cells Prokaryotic before nucleus Eukaryotic true

5. Eukaryotes Has a nucleus with a nuclear envelope
Bigger and more complex than prokaryotes
Have membrane bound Organelles (golgi, ER, lysosomes…etc)
DNA – double-stranded and forms chromosomes (highly organized)
Can be uni- OR multicellular organisms
Ex: animals, plants, fungi

6. Prokaryotes NO nucleus NO membrane bound organelles (just ribosomes)
ALL are unicellular
Smaller than eukaryotic cells
Forerunner to eukaryotic cells (smaller and more simple)
DNA – single strand and circular
Ex: ALL Bacteria 6

7. Similarities Contain all four biomolecules Have ribosomes Have DNA
(lipids, carbs, proteins, and nucleic acids)
Have ribosomes
Have DNA
Similar Metabolism
Can be unicellular
Have cell/plasma membranes or cell wall
