How do pili help bacteria?

Answer 1

Pili are structures that extend from the surface of some bacterial cells.
These are hollow, non-helical, filamentous appendages.
(https://tutor.hix.ai) and look a lot like small hairs projecting from the cell membrane.

Pili are shorter than flagella and they are not involved in motility. They are used to attach the bacterium to the substrate upon which it is living. They are made up of special protein called pilin. True pili are only present on gram negative bacteria.

They are primarily involved in the mating process between cells called conjugation in [bacteria].(https://tutor.hix.ai). This is when genetic material is transferred from one bacterium to another in a sort of sexual way.

they also help in movement of the bacteria see the video belows which explain how pili are used for movement

Pili, also known as fimbriae, help bacteria by allowing them to adhere to surfaces, including host tissues. This adherence is crucial for colonization, biofilm formation, and initiating infections. Pili can also facilitate the transfer of genetic material between bacteria through a process called conjugation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
