How do plant cells use flagella?
Well the flagella works as a propeller to help the cells move. However plant cells dont actually have flagella or cilia because they dont need to move. Some plants (bryophytes?) have motile sperm that have flagella. Also, only prokaryotic flagella work like propellers. Eukaryotic flagella whip back and forth rather than rotating.
Aside from flagella what other structures cause bacteria to move?
Flagella
What appendage does a motile bacteria possess?
Motile bacteria possess flagella or flagellum if just one, which they rotate much like the propeller on a ship through a complex protein 'motor' situated in the cell membrane. They can be located singularly at one end of the cell, singularly at both ends (never too sure how they get anywhere!), as groups at the ends of the cell or over the entire surface.
What are the difference in the flagella in prokaryotic and eucarkaryotic?
Eukaryotic flagella are quite different in structure and function to prokaryotic flagella.Bacterial flagella (as opposed to archaeal flagella - go to http://en.wikipedia.org/wiki/Flagellum#Archaeal to investigate differences between bacterial and archaeal flagella) are composed of the protein flagellin, which is coiled around into a stiff filament. Movement of a bacterial cell is generated by rotation of the filament, a bit how like a propellor works. Reversing direction of rotation can change direction of movement.In eukaryotic flagella, the structure is more complex. The base of the eukaryotic flagella houses the foundation of the structure. Nine microtubule groups, each consisting of three microtubules, form the base of the flagella. Further away from the cell, the flagella is made up of two microtubule's connected by a bridge. Radial spokes branch out to nine pairs of microtubules that form a circle around a flagella transverse section (if you chop it in half and look at the exposed inside).A eukaryotic flagella moves its cell by sliding adjacent pairs of microtubules, which causes the flagella to bend. This bending creates movement. To see a good example, watch this video: http://www.britannica.com/EBchecked/topic-video/209243/16501/Movement-of-eukaryotic-flagella-in-real-time-and-slow-motion
How does flagella work?
rotation of the flagellum is powered by a proton motive force (pmf) that is established when proteins associated with the basal body transport protons across the cell membrane, creating a charge differential across the membrane.
Why does a bacteria have a flagella?
Some bacteria have flagella, some only have one flagellum, and some just float around like a leaf in a river
Can flagella be pathogenic?
Flagella is a part of the cell which allows the cell to move. Bacteria which have flagella are not always pathogenic. Some, like Heliobacter pylori have a flagella and cause stomach ulcers in some patients. Thus, a flagella is not an indication of pathogenicity.
What is the whip-like appendage called on some bacteria?
Some bacteria have a whip-like tail called aflagellum. This structure is essential for locomotion, or motility.
What is Tiny whip like tails that help bacteria move?
it is the flagella funny name but you would probably wish some bacteria dident have one

Flagella
Can bacteria have the ability to move around?
Yes bacteria do move from place to placeyes bacteria move from place to places when people share from a straw, blood getting into someone else body, when you sneeze or cough on someone and not washing your hands after using the bathroom and before eating
What is is a di flagellate?
cells with one or more flagella
How does a bacteria cell move itself?
There's not THE ONE way how bacteria move. some are enabled to diapedeses, others have flagella, others use the flow of their environment to get transported, others use parts of their host cells moving machinery,...
What aids bacteria in movement?
Bacteria may have one of two external structures for powered movement: flagella or cilia. Also bacteria are often capable of "flowing" to move by using internal mechanisms.
What are parasitic flagellates?
of Flagellum
Did any bacteria exhibit true motility?
Although not all exhibit motility, many do by means of structures, such as flagella, axial filament, or secreted slime. Different types of bacteria use these methods for self-propelled motion.
