Q

What is the cell wall in prok made out of?

A

Peptidoglycan
To identify 2 kind of cell wall
(Gram stain)
Gram+=think wall and stain is purple
Gram-= thin wall with outer lipid layer and stain is pink

Q

What is a capsule and what is it made out of and its function?

A

It is additional layer of carbohydrates made out of polysaccharide covering cell wall.
Function:prevents cell from desiccation and drying.
And protect it from phagocytosis (engulfing) by larger molecules by sticking cells together
