Answer
The glycocalyx is a glycoprotein and glycolipid covering that surrounds the cell membranes of some bacteria, epithelia, and other cells.
Solution
a
Structure: The glycocalyx is composed of polysaccharides and/or polypeptides. It can be either a capsule, which is a well-organized and firmly attached layer, or a slime layer, which is loosely attached and unorganized
b
Function: The glycocalyx serves several functions, including protection against desiccation, resistance to phagocytosis by host immune cells, and aiding in the adherence to surfaces, which is crucial for the formation of biofilms
Key Concept
Glycocalyx is a protective and adhesive layer surrounding some cells.
Explanation
The glycocalyx helps bacteria evade the immune system, adhere to surfaces, and form biofilms, which are essential for their survival and pathogenicity.
