Average size is .2-2.0 in diameter and 2-8 micrometers in lenght
-Monomorphic; Bacteria that only has a single shape, cannot alter its shape.
-Pleomorphic; The abillity of certain bacteria to alter their shape and size in response to environmental conditions.
What are the basic cell morphology and arrangements of prokaryotic cells? learn to describe them!!
Cocci; they are in round shaped
-Diplococci; two cocci together
-Streptococci; arranged in a que. ie ......
-Tetrad four round cocci stuck together in the same plane
-Sarcinea 8 cocci arranged in a cube;
-Staphylococci; a cluster of cocci
Bacilli; Bacteria shaped like a rod
-Single bacillus looks like a rod
-Diplobacilli; two bacilli
-Streptobacilli; several bacilli stuck together at each end as to form one long rod
-Coccobacillus;shaped like cocoa bean size 1micrometer
Spiral;
-Vibrio shaped like a sausage
-Spirillum; shaped like a thick wine cork remover

What are the structural componets of a prokaryotic cell?
Glycocalyx(capsule)
-location; outside the cell wall
-Composition; polysaccharides/polypeptides
-Function; attachment, avoid phagocytosis, biofilms, controlling nutrients/ dehydration
Flagella; Flagella proteins are H antigens
-indentify as serovars of bacteria (stains)
-Function; Cellular movement
-Arrangements of flagella
-peritrichous; has flagella all around the cell
-Monotrichous and polar; has only one flagella
-Lophotrichous and polar has several flagella coming out of just one part of the cell only
-amphitrichous; has flagellas in both ends of the cell opposite to each other.
