Q

What are the major prokaryotic cell morphology types?

A
  1. Coccus - spherical
  2. Bacillus - Rod shaped
  3. Spirillum - spiral Forms
    Shape depends on the age and environment of the bacteria

Q

Define Capsules

A

Firmly attached to the cell wall
Chemical composition varies depending on the species (Polysaccharide or polypeptide)
Protects the pathogenic bacteria from being engulfed by host cells (PHAGOCYTOSIS)

Q

Define how the prokaryote reproduces

A

Reproduce via Binary Fission
Increase in cell size, DNA replication beings, cell pinches in half through area of new cell wall deposition, completion of cytokinesis.
