Clincially Significant Bavteria

Question 1

What are the major prokaryotic cell morphology types?

Answer 1

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

Question 2

What are the key structures of the prokaryotic?

Answer 2

Flagella, Cell wall, Plasma Membrane, cytoplasm, Ribosomes, Pilus, chromosomes

Question 3

Define Capsules

Answer 3

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)

Question 4

Define Endospore

Answer 4

Structures formed by some bacteria for survival during adverse environmental conditions.

Question 5

Define Binary Fission

Answer 5

One cell Splitting into two

Question 6

Define Flagella

Answer 6

Bacterial Movement
Long filamentous appendages used for propulsion and motility
Role: directional movement, chemotaxis (movement to or away from a chemical stimulus)

Question 7

Define how the prokaryote reproduces

Answer 7

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.
