Transcript of Prokaryotic Cells

Prokaryotic Cells
Reem Al-Mansoori and Noora Khalid
10GA
Parts of the Cell
1.Capsule
2.Cell Wall
3.Plasma Membrane
4.Cytoplasm
5.Ribosomes
6.Plasmid
7.Pili
8.Bacterial Flagella
9.Nucleoid (circular DNA)
Function:
it enhances the ability of bacteria to cause disease. It protects cells from Engulfment by eukaryotic cells.

Composition:
it usually consist of polysaccharides but can be composed of other material.
Function:
Prevents cell from bursting in a hypo-tonic environment.

Composition:
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.
Function:

carry genes associated with resistance to antibiotics
Composition:
small circular piece of DNA
Function:
Locomotion
Composition:
made of protein Flagellin
Function:
it attaches to any surfaces
Composition:
contains lectins
. .
. .
Function:
it stores information on how to make new proteins and stores the cell's information.
Composition:
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.
Hope you enjoyed our presentation :)
