1. Eukaryotic and Prokaryotic Cells Review: cells can be broadly differentiated
into two groups: eukaryotic and prokaryotic
both eukaryotic and prokaryotic cells have a plasma membrane that acts as a
semi-permeable barrier,
contain cytosol to suspend intracellular components,
contain chromosomes with DNA,
contain ribosomes to manufacture proteins necessary for life
2. eukaryotic cell: a eukaryotic cell is composed of a membrane-bound nucleus,
which houses DNA, and organelles that are specific to each cell.
Eukaryotic cells have a size range of 10-100 µm in diameter and vary in complexity.
animal eukaryotic cells lack cell walls, while plant eukaryotic cells are characterized
by rigid cell walls
organisms made of eukaryotic cells may be single-celled (such as an amoeba) or
multi-cellular (such as a plant or animal).
3. Prokaryotic cells: Prokaryotic cells, are less complex than eukaryotic cells.
Prokaryotic cells lack a nucleus and other membrane-bound organell es.
Prokaryotic cells are also smaller than eukaryotic cells, ranging from 1 -5 µm in

diameter.
Finally, prokaryotic organisms are always single-celled and are found within the
bacteria and archaea kingdoms.
4. Prokaryotes store genetic information in a nucleoid region.: The nucleoid
region is not bound by a membrane and contains bacterial chromosomes and DNA
Prokaryotes have a less complex genome, which, therefore, contains less DNA.
Unlike eukaryotes, bacterial chromosomes are not linear, but rather circular.
5. Bacteria have plasmids: plasmids are small, circular regions of DNA.
Bacterial cells usually have dozens of plasmids, all of which carry small amounts of
