Glycocalyx (mucilage sheath) is the outermost layer of the bacterial cell envelope which consists of non-cellulosic polysacharides with or without proteins. It may occur in the form of loose sheath, called slime layer. If it is a thick coering, it is called capsule. Glycocalyx gives sticky character to the cell and is not absolutely essential for survival of bacteria. It prevents desiccation, protects from phagocytes, toxic chemicals and viruses and serves in attachment. It may give selective advantage though in certain situations.

Explanation:
Glycocalyx:
Glycocalyx is a layer of polysaccharides that lies outside the cell wall of bacteria. It can occur in different forms such as a loose sheath or a thick and tough layer.
Types of Glycocalyx:
- Capsule:
A capsule is a well-organized and tightly bound glycocalyx layer. It is thick, tough, and firmly attached to the cell wall. Capsules protect bacteria from desiccation, phagocytosis, and other environmental stresses. They also play a role in bacterial virulence by helping them evade the host's immune system.
- Slime Layer:
A slime layer is a loose, unorganized glycocalyx that is easily removed from the cell. It is more diffuse and less tightly bound compared to capsules. Slime layers help bacteria adhere to surfaces, protect them from drying out, and aid in the formation of biofilms.
Correct Answer:
In the context of the question, the loose sheath is referred to as the slime layer, while the thick and tough layer is called the capsule. Therefore, the correct answer is option B: slime layer, capsule.
