Transcript of Prokaryotic Cells
Reem Al-Mansoori and Noora Khalid
Parts of the Cell
9.Nucleoid (circular DNA)
it enhances the ability of bacteria to cause disease. It protects cells from Engulfment by eukaryotic cells.
it usually consist of polysaccharides but can be composed of other material.
Prevents cell from bursting in a hypo-tonic environment.
it varies depending on the type of organisms, but most cell walls contain a combination of major organic molecules- proteins, carbohydrates and lipids.
Function: the gel-like fluid that the cell is filled with, inside the plasma membrane, liquid with all of the cellular organelles suspended with.
carry genes associated with resistance to antibiotics
small circular piece of DNA
made of protein Flagellin
it attaches to any surfaces
it stores information on how to make new proteins and stores the cell's information.
largely composed of DNA
Prokaryotics are uni-cellular
Facts about the Prokaryotic Cell
Bacteria is an example of prokaryotic cells
They don't have any membrane-bound organelles, like the mitochondria, they also lack a nucleus.
These cells may contain extra DNA in structures called plasmids.
