Pili, also known as fimbriae, are hair-like structures found on the surface of bacteria. They play a crucial role in attachment to surfaces, which is essential for bacterial colonization and infection. The ability of bacteria to adhere to host tissues or abiotic surfaces is facilitated by pili, allowing them to establish a presence in specific environments.

In addition to attachment, pili are involved in horizontal gene transfer, particularly through a process known as conjugation. During this process, a pilus can connect two bacteria, allowing for the transfer of genetic material, which can contribute to the spread of antibiotic resistance or other traits among bacterial populations.

This dual function of pili—supporting both attachment and genetic exchange—makes them vital for bacterial survival and adaptation, distinguishing the correct answer from those that reference movement, nutrient absorption, or reproduction, which do not accurately reflect the primary roles of pili.
