What is the benefit of a capsule in a pathogenic bacteria?

Aids in virulence.

Bundles of fibrils that arise at the ends of the cell beneath an outer sheath and spiral around the cell, means of movement by spirochetes.

Axial filaments.

The glycocalyx is a very important component of?

Biofilms

When the glycocalyx is organized and firmly attached to the cell wall.

Capsule

Quorum sensing?

Chemical communication

A glycocalyx that helps cells in a biofilm attach to their target environment and to each other is called?

Extracellular polymeric substance (EPS)

Involved in forming biofilms, occur at poles of bacterial cell, evenly distributed, may adhere to each other.

Fimbriae

Sugar coat that surrounds cells.

Glycocalyx

Involved in motility and DNA transfer and come only in one or two per cell.

Pili

The glycocalyx can be made from?

Polypeptides and polysaccharides.

When the glycocalyx is unorganized and loosely attached to the cell wall.

Slime layer

Dessication

drying out
