BIO 220, Chapter 3, Flagella

axial filament

A flagellum wrapped around spirochetes, structurally identical but between cell wall and outer coating; cause cork-screw type pattern.

photosynthetic

Bacteria that can move toward light are considered _____.

stimuli

Bacteria with at least one flagellum can purposefully respond to this

monotrichous

Bacteria with just one flagellum.

peritrichous

Bacteria with many flagella all over them.

lophotrichous

Bacteria with multiple flagella at one end.

amphitrichous

Bacteria with one flagellum at each end.

run, tumble

If several flagella are present the bacteria moves through ____ and ____ process.

cell membrane

In eukaryotic cells, the flagella are extensions of this.

less

Peritrichous bacteria tumble _____ to increase motility.

360

The arrangement of the filament, the hook and the basal body allows the flagella to rotate how many degrees?

cell wall, cuticle

The axial filament of spirochetes is located between the _____ _____ and the out coating called the _____.

motility

The movement of flagella provides this.

basal body

These are embedded in the cytoplasmic membrane and the cell wall, if there is one.

flagella

These are external structures embedded in the outermost layer of some bacteria.

basal body

These is the anchor for flagella.

basal body

This functions like a propeller, spinning the hook and the filament.

hook

This is a firm, slightly bend connection that connects the filament to the basal body.

chemotaxis

This is a motility response to chemical stimuli that bacteria move toward.

phototaxis

This is the ability of bacteria to move toward light.

atrichous

bacteria that lack flagella
