Respuesta :

Short, fine projections made of protein, which serve as attachment mechanisms, exist named pili.

What are short attachment pili?

Concise attachment Pili, also known as fimbriae, allow bacteria to colonize environmental surfaces or cells and resist flushing. They are typically short and relatively numerous. Flagella and pili, two surface appendages on Methanococcus maripaludis, may both play a role in the attachment of cells to their surroundings.

Fimbriae, or pili, are filamentous, proteinaceous organelles that are expressed on the surface of bacteria. They range in length from a few hundredths of a micrometer to more than 20 millimeters, and their diameter ranges from 2 to 11 nm. Their roles include regulating DNA absorption, motility, and cell-to-cell interactions.

Therefore, the correct answer is option a. pili.
