prokaryotic cells Flashcards
types of cells
cells are divided into two major groups
prokaryotes and eukaryotes
prokaryotes
prokaryotes cell are small ,single,simple cells that lack a nucleus.
types of prokaryotes
There are two of prokaryotes bacteria and archaea
Archaea are older organisms that develop along the same time as eukaryotes
Bactria are primitive single called organisms that predate both archea and eukayotes and are more gentically different form the two
outer capsule and cell wall
The outer capsusule is also known known as a slime loyer
The cell wall of prokaryotic cells is made of pepetidogly
can
Peptidoglycan is made of sugers
cell mebrane
this mebrane is selectively permeable which means it allows some substances in and keeps other substance out
cytopasm
Gel like substance found throughout the cell
Play in a imported role becuse of the membrane bound orgenlls
appendanges
50%of all prokaryotes have a flagllum
The flagllum looks like a tail and acts as a propellor to help the cell move
Pilli and fimbraine are hair like appendange on the outer surface of the cell that aid in movement and the transfer of genetic information
