Prokaryotic vs. Eukaryotic Cells
April 18th and 19th, 2016
2
Difference in Cells Cells fall into two broad categories, depending on whether they contain a nucleus or not. The nucleus is a large membrane-enclosed structure that contains the cell’s genetic material in the form of DNA. The nucleus controls many of the cell’s activities. Eukaryotic cells have a nucleus. Prokaryotic cells do not have a nucleus.
3
Wording So many scientific terms contain Greek or Latin roots.
Karyon- means “kernel” or nucleus. Eu- means “true”. Pro- means “before”. This wording conveys the idea that prokaryotic cells evolved before nuclei developed.
4
Prokaryotes Generally smaller and simpler than eukaryotic cells.
They have genetic material that is not contained in the nucleus. The major example we can identify with is bacteria.
5
Eukaryotes Generally larger and more complex than prokaryotic cells.
Contain a nucleus in which their genetic material is separated from the rest of the cell.
