In many bacteria, the cell wall is enclosed within a slime capsule made up of:
Correct answer: A. Polysaccharides
- A. Polysaccharides
- B. Cellulose
- C. Amino acids
- D. Proteins
Explanation
The glycocalyx is an outer coating that covers the outside of the bacterial cell wall. The glycocalyx exists in two forms i.e., capsule and slime. The capsule is a condensed layer that is relatively tightly associated with the underlying cell wall and gives sticky or gummy nature to the cell, whereas, slime is a more loosely attached layer that gives slimy or slippery nature to the cell and can be removed from the cell more easily. Generally, the glycocalyx is made of polysaccharides. However, in some cases, protein can also be present.
