What makes the bacterial cell move?
Bacterial cells can move by many ways, including "swimming" through water via the bacterial flagellum (although at the scale of a bacterial cell, the intermolecular forces between water molecules become so great that swimming would be more like drilling through sand or very thick mud). The bacterial flagellum has achieved some fame through the Intelligent Design movement as the poster boy ofirreducible complexity. However, science has now answered how the bacterial flagellum probably evolved (scientists have identified a structure very simple to the bacterial flagellum that injects poison into other cells) and Michael Behe's "theory" irreducible complexity is thoroughly debunked.
What protein is the filament in a bacterial flagellum made of?
The filament in a bacterial flagellum is made of a protein called flagellin. Flagellin forms the helical structure of the flagellum filament, providing the bacterium with motility.
What has flagellum?
Bacteria, some cells
Do plants have bacterial flagellum?
No
Is the flagellum found in plant or animal cells?
Flagellum can be found in some prokaryote and eukaryote cells but not in plant cells. Plant cells have cell walls to provide rigidness and that would contrast with flagellum, which purpose is to allow flexibility and movement.
What are some examples of irreducibly complex systems?
An eye and flagella Creationists commonly put forward the eye or the bacterial flagellum as examples of irreducibly complex systems that could not have evolved from simpler systems. However, neither the eye nor the bacterial flagellum is really irreducibly complex. Scientists can point to primitive eyes, going back to merely light-sensitive areas of skin. An evolutionary progression can readily be deduced. The bacterial flagellum is a complex structure that allows a bacterium to move around in a liquid, and indeed the flagellum would not work as such if any key component were removed. However, there are similar bacterial structures that contain most, but not all, the components of the flagellum and which perform useful functions. The type III secretory system, a molecular syringe which bacteria use to inject toxins into other cells, is one such structure. Whether the bacterial flagellum evolved from the type III secretory system or from another bacterial system, the existence of the type III secretory system proves that the bacterial flagellum is not irreducibly complex.

What part of bacterial cells aids in movement?
Motile
Do the cells have an interior or posterior flagellum?
suck my balls
What is the function of a bacterial fiagellum?
A flagellum is a hair like structure that protrudes from the body of a prokaryotic or eukaryotic organism. Its primary function is for locomotion.
How does flagellum relate to creation?
Briefly, flagellum relates to creation of life because of "irreducible complexity." Even Darwin himself stated that if anyone found a biological structure that can not live over time to become more complex, then his theory would fall apart. Flagellum provide that proof. Irreducible complexity is if any part is missing, or defective, the machine won't work. This includes biological machines. Flagellum can not be made gradually because they need many working parts for anything to work or continue.
A long hair like structure use for movement?
In animal cells: cilia (many cilia per cell) In bacterial cells: flagella (only one per cell)
