Appearance. A taproot has a main root, similar in appearance to a carrot, which is also a taproot. In most cases, smaller, auxiliary roots grow laterally all along the main taproot. A fibrous root system is a mass of small roots, with an appearance of a mass of fibers. It can resemble a bird's nest or a ball of yarn. The roots are typically only a few inches long and branch frequently, similar to the canopy of a tree.

Fimbriae are found in gram negative as well as gram positive bacteria but are shorter in length as compared to pili. Pili are longer than fimbriae and there are only a few per cell.
