The composition of the glycocalyx can differ among various bacteria, with some displaying a loose sheath called the slime layer. This variation in glycocalyx structure plays a crucial role in the bacterium's interactions with its environment, such as protecting it from desiccation and facilitating adherence to surfaces.

Introduction to the Glycocalyx
The glycocalyx is a polysaccharide-rich layer found on the surface of many bacteria, playing a crucial role in their interaction with the environment. Its composition varies significantly among different bacterial species.
Variability in Composition
- The glycocalyx can be either a capsule or a slime layer.
- Capsules are organized and tightly bound structures, providing protection from phagocytosis and desiccation.
- Slime layers are more loosely associated with the cell surface, offering less protection but facilitating adherence to surfaces and biofilm formation.
Presence in Bacteria
- Not all bacteria possess a glycocalyx:
- Some bacteria, such as Escherichia coli, may have a capsule, while others may not have any glycocalyx at all.
- The presence of a glycocalyx can be an important factor in pathogenicity.
Functionality
- The glycocalyx serves multiple functions:
- Adhesion: Helps bacteria attach to surfaces and each other, forming biofilms.
- Protection: Shields bacteria from environmental threats, including immune responses.
- Nutrient Capture: Assists in the absorption of nutrients from the environment.
Conclusion
In summary, the glycocalyx can vary widely among bacterial species, existing as either a capsule or a slime layer, or may even be absent. Its composition and structure play significant roles in survival, pathogenicity, and ecological interactions. Thus, option 'C' is correct as it accurately reflects the diversity of the glycocalyx among bacteria.
