On the other hand, Microvilli increase the surface area They are involved in the bacterial conjugation, attachment to the surface and motility. Pili. Fimbriae are finger-like projections and a part of fallopian tubes lie closer to the ovary. Microvilli: Microvilli mainly occur in the columnar epithelial cells of the small intestine and kidney tubules. What is the difference between Pili and Fimbriae? Cilia are also found in the vertebrate ear, surrounded by active-based stereocilia, promoting the hearing. are narrow and long hair like protuberances from the apical surface of some E. coli cells can have up to 300 of these organelles. Pili structure.Pili are generally shorter and thinner than flagella and are made from structural proteins called pilins.
