Bacteria that lack fimbriae are less likely to
adhere to cell surfaces
swim through bodily fluids
synthesize proteins
retain the ability to divide

The correct answer will be option- adhere to cell surfaces.

Explanation:

The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.  

The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.

Thus, option- adhere to cell surfaces is the correct answer.
