Not all bacteria are nonmotile. The reason some bacteria cannot move freely is because they lack one of the 3 known types of motile structures:
1.-Flagella: they are protein (flagellin) based threads, many times the bacterias own length. They are anchored in the cell wall and rotate, causing the flagella to spin in a whip-like pattern, thus propelling the bacteria.
2.-Gas vesicles: some bacteria use small gas bubbles produced inside of them to move up an down the water column, like aquatic bacteria that need to rise to the surface to receive more sunlight.
3.-Sliding: a few bacteria have been found to move only over solid surfaces using a theorized caterpillar-like mechanism akin to the tread wheels of a tank.
All bacteria that do not have one of the above mentioned movement types are termed nonmotile. Under the microscope, they seem to move in random directions by what is called Brownian movement, which is a random displacement caused by collisions with other cells, microcurrents, etc.
They are motile if oxygen is present.
Mastigophores use flagella for motility.
There are many Bacterias in our body some are e.coli in intestine
because they take over other bad bacterias and they can be good or bad
molds
They are motile if oxygen is present.
Mastigophores use flagella for motility.
Fungi are non motile means they are not able to move.
Bacterias do not reproduce sexually.
yes.some of the bacterias are useful but some are not.some specific type of bacterias are using as medicine also.
Bacterias. But be careful, some bacterias are awful and some are good bacterias where you can find them in yoghart or milk.
There are many Bacterias in our body some are e.coli in intestine
Some bacterias are nice but some are not like bacterias that wont harm you are nice ones and the one who harms arr viruses
it depends on the type of the bacteria. also beneficial bacterias outnumber the population of harmful bacterias.

Spore-forming Protists: Sporozoans are nonmotile unicellular parasites that form spores.
each spermatid has the correct chromosomal number for fertilization (n), but is nonmotile.
