Prokaryotic:
A single cell organism, no nucleus, have nucleoid to contain DNA
e.g. bacteria

Stem Cell Types:
Embryonic cells: Controversial (taken from embryo) but can differentiate
into different cells, can cure disease
Adult Cells: Can ask permission but can't differentiate like embryonic, only to the area they were taken from e.g. lung
Meristem cells: can make all types of cells from plants at any age, found close to tip of shoot
