Pili (also called fimbriae) are straight filaments arising from the bacterial cell wall, making the bacterium look like a porcupine. Common pili or fimbriae are often involved in adherence (attachment) of bacterial cells to surfaces in nature. Microvilli (singular: microvillus) are protrusions on the cell surface, which increase the surface area of the cell. The glycocalyx layer, which covers microvilli, allows the binding of substances with the microvilli that is to be absorbed. microvilli. Such a structural arrangement is absent in microvilli. Pili can serve as adherence factors (in which case they are called adhesins). They enable the bacteria to bind to specific receptor structures and thereby to colonise specific surfaces.

A tropical tree, Canarium ovatum, native to maritime Southeast Asia, New Guinea and northern Australia, and cultivated in the Philippines for its nuts. Columnar epithelial cells of the respiratory and uterine tube contain cilia. How do you calculate the ideal gas law constant? The diameter of pili is higher than that of fimbriae. These microfilaments are held together to form bundles by cross-linking proteins known as villin and fimbrin. Microvilli are shorter and narrower when compared to cilia. Unlike microvilli, cilia extend slightly into the cell and are anchored via a special structure called basal body, which is made of microtubules. Cilia are motile and involved in the rhythmic movement of either the whole cell or external objects like microorganisms, dirt, and mucus over the cell surface. Cilia are longer than microvilli. Fimbriae are long filamentous polymeric protein structures located at the surface of bacterial cells.
