facilitates cell surface interaction, adhesion, and protection.

Question 5

The sticky slimy polysaccharide external to cell wall.

Answer 5

GlycocalyxF

Question 6

Function of glycocalyx:

Answer 6

Prevents the cell from attacks and stress

Question 7

Give examples of glycocalyx:

Answer 7

Biofilm, capsule, slime layer.

Question 8

The thick protective layer secreted by bacteria that function as adhesive, protects from desiccation and phagocytosis.

Answer 8

Capsule

Question 9

Capsule is present in what type of cell wall bacteria?

Answer 9

Gram negative bacteria

Question 10

Think layer that can easily be deformed and detached: that prevents the bacterial cell from drying and trap nutrients inside.

Answer 10

Slime layer
