Pili are filaments that help bacteria stick to the surface and exchange plasmid through conjugation.
Genetic exchanges among bacteria occur by several mechanisms. In transformation, the recipient bacterium takes up extracellular donor DNA. In transduction, donor DNA packaged in a bacteriophage infects the recipient bacterium. In conjugation, the donor bacterium transfers DNA to the recipient by mating.
There are two types of pili found on some bacteria. Sex pili are used by bacteria to transfer plasmids during conjugation. Common pili (fimbrae) are used to stick to surfaces.

Pili are tiny, hollow projections that are used in attachment to surfaces. They have nothing to do with motility. There are two types 1.) long conjugation pili, that aide in transfer of genetic material. 2.)Attachmetn pili or fimbriae, that help bacteria adhere to surfaces. Hope that helps!!!

Pillus (plural form is pilli), usually Type IV pilli, are used in conjugation to transfer plasmids from one bacteria to another. Other pilli are used for adhesive purposes like you said.
