Pilus, or plural pili, is a short, hair-like appendage found on the surface of some eubacteria cells. It acts as a type of "molecular grappling hook" that helps bacteria attach to surfaces, including other cells. Pili can be involved in various functions such as mediating bacterial attachment, establishing communication between cells, and facilitating the transfer of genetic material through a process called conjugation.
Pilus, or plural pili, is a short, hair-like appendage found on the surface of certain eubacteria (also known as true bacteria). Pili play various roles in bacterial cells, primarily involved in processes like attachment, motility, and DNA transfer between cells. They help bacteria adhere to surfaces or other cells, aiding in the formation of biofilms and colonization. Some pili also enable bacteria to move around by a process known as twitching or gliding motility. Another important function of pili is facilitating the transfer of genetic material through a process called conjugation, allowing bacteria to exchange DNA and acquire new genes.
