In endospore formation, the bacterium divides within its cell wall. Microvilli are the minute finger- like elongated projections of the plasma membrane which exhibit a core of thin microfilaments. Small, generally microscopic, vibrating appendages lining certain organs, as the air passages of the higher animals, and in the lower animals often covering also the whole or a part of the exterior. This article explains, 1. Small, generally microscopic, vibrating appendages lining certain organs, as the air passages of the higher animals, and in the lower animals often covering also the whole or a part of the exterior. Microvilli are surrounded by a glycocalyx layer. Bundling proteins like fimbrin,villin and epsin are involved in the cross-linking of microfilaments of microvilli. Unravel the Riddle: Get to Know the Difference Between Row vs Columns! Also, cilia can be found in some specialized cells like the sensory cells of a vertebrate ear as conventional cilia surrounded by actin-based stereocilia, which are responsible to provide initial sensory input for hearing. The main function of pili is gene transfer (by conjugation) and attachment. A small, fringe of finger-like cellular projections and it is located at the end of the fallopian tube is known as fimbria. microvilli. Endospore formation is usually triggered by lack of nutrients, and usually occurs in Gram-positive bacteria.
