Suppose a bacterium had the opportunity to form a glycocalyx, a flagellum, a pilus, or a spore. Which do you think it might choose? Why?

Explain in 1-2 paragraphs

Expert Solution

A flagellum helps the bacterial cell to move from one location to another. A pilus helps for attachment of bacterial cells to any surface and sometimes in conjugation with other bacterial cells (sex pilus). Spores are extremely resistant structure formed by the bacteria when they encounter unfavourable conditions and spores can survive for long periods and withstand sterilization techniques.

Glycocalyx is a type of capsule found on the surface of bacteria and composed of a thin layer of tangled polysaccharide fibres, rarely amino sugars or peptides. Glycocalyx provides the bacteria with many important features.

Helps the bacterial cell to adhere with other surfaces.
Protects the bacterial cell from engulfment by host immune cells or protozoans, a process termed as phagocytosis.
Provides protection against antimicrobial agents.
Protect the cells from drying or desiccation.
Capsular materials can serve as a reserve of carbohydrates.
Helps the bacteria to form biofilm and provide protected and enriched environment.

The bacteria might choose glycocalyx than the other cell structures as glycocalyx provides immense benefits to the bacteria.

QUESTION Check all of the following that are true for the glycocalyx. Eukaryotic glycocalyx is attached to the cell via membrane lipids. Eukaryotic glycocalyx is secretd from the cell. Prokaryotic glycocalyx is made mostly of proteins. Eukaryotic glycocalyx is important for recognition of hormones and cell signaling. Prokaryotic glycocalyx is important in protection from the host immune system. Prokaryotic glycocalyx is interior to the cell membrane.
