A dimorphic root system is a plant root system with two distinct root forms, which are adapted to perform different functions. One of the most common manifestations is in plants with both a taproot, which grows straight down to the water table, from which it obtains water for the plant; and a system of lateral roots, which obtain nutrients from superficial soil layers near the surface.

Dimorphic root systems: roots with two distinctive forms for two separate functions; Fine roots: typically primary roots <2 mm diameter that have the function of water and nutrient uptake. They are often heavily branched and support mycorrhizas. These roots may be short lived, but are replaced by the plant in an ongoing process of root 'turnover'.
Dimorphic root systems, plant roots with two distinctive forms for two separate functions; Sexual dimorphism, a phenotypic difference between males and females of the same species; Nuclear dimorphism, when a cell's nuclear apparatus is composed of two structurally and functionally differentiated types of nuclei
The vegetative (somatic) structures of vascular plants include two major organ systems: (1) a shoot system, composed of stems and leaves, and (2) a root system. These two systems are common to nearly all vascular plants, and provide a unifying theme for the study of plant morphology.
Replacement of a tap root system by a fibrous root is seen in onions, tuberose (Polyanthes tuberosa), grasses, etc. Fibrous roots from normal-stem nodes are seen in grasses like maize, sugarcane, bamboo, etc. Fibrous roots from nodes help in the survival of the plant and thus in vegetative reproduction, when the plant's base is damaged or cut ...
