Prokaryotes are unicellular organisms, found in all environments. Prokaryotes are the largest group of organisms, mostly due to the vast array of bacteria which comprise the bulk of the prokaryote classification. Prokaryotes do not have an organized nucleus. Their DNA is kind of floating around the cell. It's clumped up, but not inside of a nucleus.

No nuclear membrane: (genetic material dispersed throughout cytoplasm) the DNA is clumped in an area but there is no organized nucleus with a membrane. Simple internal structure: Prokaryotes do not usually have any organelles. They will probably have ribosomes inside of their cells, but ribosomes are not technically considered organelles.

very small: Because they don't have all of the normal cell machinery, they are limited in size. Most primitive type of cell: (appeared about four billion years ago)

Eukaryotes are generally more advanced than prokaryotes. There are many unicellular organisms which are eukaryotic, but all cells in multicellular organisms are eukaryotic. Eukaryotes are cells that can do anything. They are the cells that have helped organisms advance to new levels of specialization beyond imagination. You wouldn't be here if eukaryotic cells did not exist.

organized nucleus: Eukaryotic cells have a "brain" for the cell. They have a discreet area where they keep their DNA. It is also said that they have a "true nucleus.“ Complex internal structure: Eukaryotic cells usually have organelles. They might have mitochondria, maybe a chloroplast, or some endoplasmic reticulum. They have parts that work to make the cell a self-sufficient organism.

Bigger than Prokaryotic: Generally, eukaryotic cells are a couple hundred times the size of a prokaryotic cell Eukaryotic cells can get very large. There are even some extreme examples called plasmodial slime molds that can be a meter wide. The cell is multinucleated (many nuclei) and it gets huge. Appeared approximately one billion years ago Eukaryotic cells are divided into Animal and Vegetal cells.
