What structure if present let bacteria be motile?
Most motile bacteria move by means of flagella, if present. Motile means that they are capable of motion. Flagella is the plural of flagellum.
Does bacteria live in a moist environment?
One of the primary means of bacterial locomotion is the bacterial flagellum, a rotary " motor " that propels the bacteria whip like through water.
Is a flagellum the tube through which semen enters the male urethra?
The flagellum is part of the sperm that allows it to swim, the ejaculatory duct is what brings the sperm to the urethra.
What is the basal body?
The basal body is a structure that anchors the base of the flagellum and allows it to rotate.
What kind of plant can move on its own?
Green algae have a tail (flagellum) that allows it to move around.
What structure do E. coli have which allows them to move?
Bacteria can move in three main ways. First is by a whip-like tail called a Flagellum. Second, is by hair like structures that cover the outside of the cell. These are called Cilia. Third is by Psueudopodia, where the cell reaches out a "foot," and pulls itself along. (Psuedopodia means "False Foot")
How does flagellum help sperm?
The flagellum, a long whip-like structure, helps sperm to swim and move towards the egg. The waving motion of the flagellum propels the sperm forward through the female reproductive system. This movement is essential for sperm to reach and fertilize the egg.
The structure that sticks out from the cells surface and allows it to move is an?
The structure that sticks out from the cells surface and allows it to move is known as cilia. Some cells also use flagellum to move.
What is the function of a sperm's cell's flagellum?
the nucleus is where DNA is stored and the flagellum is another major part commonly linked to the sperm cell.
Some bacterial cells have a flagellum?
The bacterial flagellum is made up of the protein flagellin,this "hook" allows the axis of the helix to point directly away from the cell. The basal body has several traits in common with some types of secretory pores.
What are some examples of 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.
