Taproots can also serve to store food reserves, making them even more self-sufficient and resilient. Dicots, one of the two divisions of flowering plants (angiosperms), start with a taproot,[2] which is one main root forming from the enlarging radicle of the seed. The fibrous root is the other type of root system where the root develops from the stem in the form of thin and moderately branching roots without any primary root. For most plants species the radicle dies some time after seed germination, causing the development of a fibrous root system, which lacks a main downward-growing root. It branches off to secondary roots, which in turn branch to form tertiary roots. Many plants with taproots are difficult to transplant, or even to grow in containers, because the root tends to grow deep rapidly and in many species comparatively slight obstacles or damage to the taproot will stunt or kill the plant.
