Prokaryotic Cells Vs. Eukaryotic Cells

All cells fall into one of the two major classifications of either prokaryotic or

All cells fall into one of the two major classifications of either prokaryotic or eukaryotic.

What’s the difference between prokaryotes and eukaryotes? l Prokaryotic cells were here first and

What’s the difference between prokaryotes and eukaryotes? l Prokaryotic cells were here first and for billions of years were the only form of life on Earth. All prokaryotic organisms are unicellular l Eukaryotic cells appeared on earth long after prokaryotic cells but they are much more advanced. Eukaryotic organisms unlike prokaryotic can be unicellular or multicellular.

Characteristics of Prokaryotes l Prokaryotes are the simplest type of cell. l Oldest type

Characteristics of Prokaryotes l Prokaryotes are the simplest type of cell. l Oldest type of cell – original cells l Prokaryotes are the largest group of organisms l Prokaryotes unicellular organisms that are found in all environments.

Characteristics of Prokaryotes l Prokaryotes do not have a nuclear membrane. l Prokaryotes do

Characteristics of Prokaryotes l Prokaryotes do not have a nuclear membrane. l Prokaryotes do not have membrane-bound organelles. l Prokaryotes have a simple internal structure. l Prokaryotes are smaller in size when compared to Eukaryotes.

Shapes of Prokaryotes Cocci = spherical (round) l Bacillus = (rod shaped) l Spirilla

Shapes of Prokaryotes Cocci = spherical (round) l Bacillus = (rod shaped) l Spirilla = helical (spiral) l

Characteristics of eukaryotes l Eukaryotic cells are much newer l Eukaryotes are generally more

Characteristics of eukaryotes l Eukaryotic cells are much newer l Eukaryotes are generally more advanced than prokaryotes l Nuclear membrane surrounds linear genetic material (DNA)

l Eukaryotes have several different parts. l Eukaryote’s organelles have coverings known as membranes.

l Eukaryotes have several different parts. l Eukaryote’s organelles have coverings known as membranes. l Eukaryotes have a complex internal structure. l Eukaryotes are larger than prokaryotes in size.

How do the differences line up? Prokaryotes l Organelles lack a membrane Eukaryotes l

How do the differences line up? Prokaryotes l Organelles lack a membrane Eukaryotes l Organelles covered by a membrane l Ribosomes are the only organelles l Multiple organelles including ribosomes l Genetic material floats in the cytoplasm (DNA and RNA) l Membrane covered Genetic material

How do the differences line up? Prokaryotes l Circular DNA Eukaryotes l Linear DNA

How do the differences line up? Prokaryotes l Circular DNA Eukaryotes l Linear DNA l Unicellular l May be multicellular or unicellular l Cells are smaller in size l Cells are larger in size l Has smaller number of organisms l Has larger number of organisms

How do the differences line up? Prokaryotes l Original cells Eukaryotes l Newer cells

How do the differences line up? Prokaryotes l Original cells Eukaryotes l Newer cells

How do the similarities line up? Lets See!!! l l Both types of cells

How do the similarities line up? Lets See!!! l l Both types of cells have cell membranes (outer covering of the cell) Both types of cells have ribosomes Both types of cells have DNA Both types of cells have a liquid environment known as the cytoplasm
