Eventually, the available food always runs out and then the bacteria enter a state that is similar to sleep, where they try to use as little energy as possible, in order to have a chance to reproduce when food is available once again. This energy-saving state is called “dormancy,” and we refer to these bacteria as “dormant.”.

Bacterial binary fission is the process that bacteria use to carry out cell division. Binary fission is similar in concept to the mitosis that happens in multicellular organisms (such as plants and animals), but its purpose is different.

Some bacteria have a single, tail-like flagellum or a small cluster of flagella, which rotate in coordinated fashion, much like the propeller on a boat engine, to push the organism forward. The hook: Many bacteria also use appendages called pilli to move along a surface. What structure do some bacteria use to move? Flagella. What is the difference between gram-positive bacteria and gram-negative bacteria? A rotating, corkscrew-like propeller is required to move a bacterium forward. Scientists call the development of this shape “supercoiling,” and they now know how bacteria do it after more than 50 years of research. Egelman and his colleagues discovered that the protein that makes up the flagellum may exist in 11 different states using cryo-EM.

All bacteria, both pathogenic and saprophytic, are unicellular organisms that reproduce by binary fission. Most bacteria are capable of independent metabolic existence and growth, but species of Chlamydia and Rickettsia are obligately intracellular organisms.

Pili- are short hair like protein structure on the surface of some bacteria that help bacteria connect to each other and to surfaces, such as those of a host cell. b. Flagella- propel the cell by rotating in a whip like motion. It also allows the prokaryotes to move towards food and away from danger.Moreover, some parasitic bacteria can induce actin polymerization to form a tail and move inside the host cell. These motility types and others are included in a recent re-classification based on the structure of the force-producing motor . Different motility types are not mutually exclusive.
