* All of our cells have a nucleus.  

What makes our cells different from bacteria?  Our cells have a nucleus. The cells in our bodies have a nucleus. What is inside the nucleus? DNA is inside. 

 

Very Important Concept: Different between Prokaryotic and Eukaryotic cells. (This is on the EOC test and a large part of it as well.)

 

Eukaryotes:

DNA is a nucleus. Has cell membrane, but no cell wall

 

It has a membrane bound organelles (has an outer boundary that allows materials in and out) .

 

Larger in size

 

Eukaryote Classification: Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia

 

Prokaryotes:

Has cell wall and cell membrane. No nucleus; lacks most of the organelles that Eukaryotes have. 

 

They lack membrane-bound organelles.

 

Smaller in size than Eukaryotes

 

Classification: Kingdom Eubacteria and one other

 

Similarities between Eukaryotes and Prokaryotes:

Both have:

Cell/plasma membrane

DNA

Ribosomes (makes protein)

Cytoplasm
