Taproot - Wikipedia
A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. [1] In some plants, such as the carrot, the taproot is a storage organ so well developed that it has been cultivated as a vegetable.
Taproot | Definition, Facts, & Examples | Britannica
Taproot, the main root of a primary root system, growing vertically downward. Most dicotyledonous plants produce taproots, some of which are specialized for food storage. In other plants, the initial taproot of the seedling is replaced by a fibrous, or diffuse, root system.

2023年7月27日 · A taproot is the thick main root of a plant that grows vertically downward into the soil from which smaller lateral roots branch out. Taproots have a prominent central axis, unlike fibrous roots that are fine and branching.
11.3: Root Systems - Biology LibreTexts
The large, central root (what we call a carrot) is a taproot and has many much smaller lateral roots that emerge from the sides. These are not root hairs, which would appear more like a microscopic fuzz at the ends of these lateral roots.
Tap Root System: Definition and Types (With Diagram)
Definition of Tap Root System: It is a mass of roots which develops from the radicle of the embryo. It consists of a tap root, secondary roots, tertiary roots and rootlets (Fig. 5.5).

2020年1月17日 · When a seed germinates it produces a shoot and a root, which is called the radicle. This radicle, in the purest sense, is a taproot. Taproot growth is under the hormonal control of auxin, the hormone that causes young shoots to …
Tap Root Diagram with Types and Examples - BYJU'S
A taproot system comprises one thick, cylindrical main root known as the primary root. Small roots that branch out from the primary root are termed as secondary and tertiary roots. A thin hair-like structure known as a rootlet can be found at the tip of the tertiary root.
Taproot System: Types, Modifications and Examples
Taproots are one of the three major types of root systems found in plants; the other two are adventitious root system and fibrous root system. Taproots arise from the radicle of a germinating embryo. The radicle of many plant species dies soon after maturation and, hence, the taproot gets converted into the fibrous root system in the later stages.
30.3: Roots - Biology LibreTexts
A tap root system penetrates deep into the soil. In contrast, a fibrous root system is located closer to the soil surface, and forms a dense network of roots that also helps prevent soil erosion (lawn grasses are a good example, as are wheat, rice, and corn).
Taproot | Parts of a Plant
Unlike the fibrous root system that has numerous branched roots, the taproot system only contains a single, bark-like root with some tiny fine roots emerging from it. Several plants, particularly dicots, normally start with a taproot with a single root forming from the seed’s enlarging radicle.
