The major similarities between the two types of cells (prokaryote and eukaryote) are:
They both have DNA as their genetic material.
They are both membrane bound.
They both have ribosomes .
They have similar basic metabolism .
They are both amazingly diverse in forms.
The major and extremely significant difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus and membrane-bound organelles , while prokaryotes do not. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells. Additional obvious differences between prokaryotes and eukaryotes include:
Size
Eukaryotic cells are, on average, ten times the size of prokaryotic cells.
Genomic composition and length
The DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes.
Cell Wall
Prokaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan.

eukaryotes has DNA in their nucleus
and prokaryotes contains the DNA in the cytoplasm
Prokaryotes are usually much smaller than eukaryotic cells.

Prokaryotic dont have nucleus, and are found only in single celled organisms. Eukaryotic cells have a nucleus, and are found in multi-cellular organisms(ex: humans)

eukaryotes have "true" nuclei containing their DNA, whereas the genetic material in prokaryotes is not membrane-bound

pro (bacteria cells only) has no nucleus/cell-bound membranes, eukar (animal/fungi/plants) has nucleus/cell-bound membranes (mitcohondria, ribosomes)

isnt one bacteria and a lot simpler (pro?) and the other has a nucleus and stuff (euk?)
been a while since bio 1
