SSC CPO 2023 PYQ — Question 94

The correct answer is option 4 i.e. Slime layer.

A glycocalyx that is a loose sheath type is called a slime layer. Unlike a capsule, which is a well-defined, rigid layer tightly bound to the cell wall, the slime layer is more loosely attached and can be easily washed away. It consists of a network of polysaccharides and is involved in protecting the bacterial cell, aiding in adhesion to surfaces, and forming biofilms. The slime layer helps in maintaining cell hydration and provides some protection against desiccation and immune responses.
