Lateral root - Wikipedia
网页Lateral roots, emerging from the pericycle (meristematic tissue), extend horizontally from the primary root (radicle) and over time makeup the iconic branching pattern of root systems. [1]
Lateral Root - an overview | ScienceDirect Topics
网页Lateral roots are the building blocks of the root system that arises from pericycle and exhibit a morphology that is similar to the primary root (Dolan et al., 1993). These roots are important for expanding the contact area of root systems to explore heterogeneous soil …
3.3: Roots - Biology LibreTexts
网页2022年7月27日 · Locate and identify characteristics of the primary root, lateral or secondary roots, and root hairs. Distinguish two major types of root systems and how they develop.
Lateral root | plant anatomy | Britannica
网页Because lateral roots are initiated in the pericycle and grow out through the cortex and epidermis, they are said to have an internal, or endogenous, origin, in contrast to the external, or exogenous, origin of leaves and the apical meristem of stems (see below Stems). Read More.
Lateral root formation and the multiple roles of auxin - Oxford …
网页2017年7月20日 · The model plant Arabidopsis thaliana possesses a tap root system, in which the primary root and lateral roots (LRs) are major architectural determinants. The phytohormone auxin fulfils multiple roles throughout LR development.
11.3: Root Systems - Biology LibreTexts
网页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.
The Systems Biology of Lateral Root Formation: Connecting the …
网页The architecture of the root system to a large extent depends on the repeated formation of new lateral roots. In this review, we discuss lateral root development from a systems biology perspective.
30.3: Roots - Biology LibreTexts
网页Summary. Roots help to anchor a plant, absorb water and minerals, and serve as storage sites for food. Taproots and fibrous roots are the two main types of root systems. In a taproot system, a main root grows vertically downward with a few lateral roots.
Lateral Root | Parts of a Plant - Plant Biology
网页Lateral roots serve as the plant’s secure anchor to the soil and they extend horizontally from the primary root. Such branching of the root can help in the uptake of water and in facilitating the extraction of nutrients that is needed for the plant’s growth and development.
Lateral Roots - Vocab, Definition, and Must Know Facts - Fiveable
网页Lateral roots help improve soil stability and prevent erosion by spreading out and creating a more extensive root network. The growth of lateral roots can be influenced by hormones like auxins, which play a key role in root development and branching.
