The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. They are also found on some vegetable organisms. Each cilium originates directly from a special structure called basal body. Cilia and microvili are two types of projections in the plasma They are shorter than flagella and more in number. 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.

Cilia: Cilia arise from the basal granules. Microfilaments are held together by cross-linking of proteins. Many bacterial cells secrete some extracellular material in the form of a capsule or a slime layer. They are found in gram negative bacteria. These microfilaments are held together to form bundles by cross-linking proteins known as villin and fimbrin. Flagellum is primarily a motility organelle that enables movement and chemotaxis. A pilus is a thin, rigid fiber made of protein that protrudes from the cell surface. Pili are shorter than flagella and they are not involved in motility.
