How do bacteria achieve motility?
A
By forming pseudopodia
B
By gliding on a slime layer
C
Through ciliary movement
D
Using flagella to propel themselves
Verified step by step guidance
1
Understand that motility in bacteria refers to their ability to move independently using various mechanisms.
Recognize that one common method of bacterial motility is through the use of flagella, which are long, whip-like structures that rotate to propel the bacterium forward.
Differentiate between other forms of motility such as pseudopodia, which are used by amoeboid cells, and ciliary movement, which is characteristic of certain eukaryotic cells, not bacteria.
Consider the mechanism of gliding motility, where some bacteria move by sliding over surfaces using a slime layer, but this is distinct from flagellar movement.
Conclude that the primary and most common method of motility in bacteria is through the use of flagella, which allows them to swim through liquid environments.
