Have the potential to cure certain diseases (such as
Prokaryotes vs. Eukaryote
Prokaryotes do not have a membrane bound nucleus
while eukaryotes do
The vast majority of prokaryotes are unicellular while
most eukaryotes are multi-cellular
Embryonic stem cells:
1. Totipotent: can give rise to any type of tissue in the body
including those cell types associated with the placenta. Has
this ability only until the eight cell stage embryo.
2. Pluripotent: (After this eight cell stage) embryo will
reorganize until the blastocyst 5 days. Found in the inner cell
mass. Can give rise to any cell except for cells in the
3. Multipotent (not embryonic): Have the ability to give rise
to multiple, but limited cell types.
