The two types of root systems in plants. The fibrous-root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root, with smaller roots branching off. The letters indicate where the root systems begin. A taproot is a large, central, and dominant root from which other roots ...
English: The two types of root systems in plants provide their stems and leaves with water and mineral. The fibrous root system (A) is characterized by many roots with similar sizes. In contrast, plants that use the taproot system (B) grow a main root with smaller roots branching off of the taproot.
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.

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 ...
Root trainer pots. Many pot designs train the roots. One example is a truncated plastic cone in which a seedling is planted. There is a drainage hole at the bottom and the main tap root tends to grow towards this.
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The phyllaries can be free or fused, and arranged in one to many rows, overlapping like the tiles of a roof (imbricate) or not (this variation is important in identification of tribes and genera). Each floret may be subtended by a bract, called a "palea" or "receptacular bract". These bracts are often called "chaff". The presence or absence of ...
Hydraulic redistribution is a passive mechanism where water is transported from moist to dry soils via subterranean networks. [1] It occurs in vascular plants that commonly have roots in both wet and dry soils, especially plants with both taproots that grow vertically down to the water table, and lateral roots that sit close to the surface.
