3.Morphology, Cell Arrangements, And Functional Anatomy Of Prokaryotic Cells

Question 1

A bacillus:

Answer 1

Is a Rod shaped bacterium

Question 2

A general term for any network of polysaccharide or protein

Answer 2

Glycocalyx

Question 3

Is important for motility and attachment and filtering of chemical compounds (antibiotics)

Answer 3

Slime layer

Question 4

“……..” or surface layer: composed of glycoproteins and lipids and polysaccharide and peptides.Released to outside of the cell produces a substance to form bio films in G+ and G-Ev and Archea system

Answer 4

S-Layer

Question 5

The function of S-Layer:

Hint:
A
M
F
Por
Imp
Avoiding

Answer 5

Attachment 
Motility
Filtration
Porous structure
Important for defense mechanism helps the bacteria to sustain in adverse conditions 

Avoiding being attacked by their competitors

Question 6

Functions of Slime layer(glycocalyx);

Hint;

Interaction
Prom
Prot
Capsule

Answer 6

To diverse microbial his interactions, both beneficial and pathogenic,

Promotes adherence (surface, host cell)

Protects bacteria cells from hostile environments and immune cells.

Capsule polysaccharide are recognized by host cells

Question 7

“………” formation represents a protected mode of growth that allows cells to survive in hostile environments and olso disperse to colonize new niches

Answer 7

Biofilms

Question 8

The structure and arrangement of “……..” differ from species to species and seem to be related to the specific environments in which the cells live. Can also be arranged on the cell body in a variety of configuration, including single polar, multiple polar

Answer 8

Flagella

Question 9

Flagella in depth:
Hint;

Outside
Made
Attached
Anchored

Answer 9

Outside cell wall
Made of chains of flagellin (made of proteins)
Attached to a protein hook
Anchored to the wall and membrane by the basal body

Question 10

Flagella proteins are:

Answer 10

H antigens

Question 11

“……” also called endoflagella, it is in spirochetes and are anchored at one end of the cell, the rotation cause the cell to move

Answer 11

Axial filament

Question 12

Types of bacterial motility:

Answer 12

• pili
• gliding motility
• twitching motility

Question 13

When it prevents osmotic lysis and are made of peptidoglycan:

Answer 13

The cell wall

Question 14

Gram positive cell wall:

Answer 14

Thick peptidoglycan

Teichoic acids

Question 15

Gram negative cell wall:

Answer 15

Thin peptidoglycan
Outer membrane
Periplasmic space

Question 16

“…….” links to plasma membrane

“…….” links to peptidoglycan

Answer 16

1. lipoteichoic acid

2. Wall teichoic acid
