what is a fibrous root?

Answer 1

Fibrous root systems have many secondary roots but not a main root. They spread through the soil in the plant's vicinity and help hold the soil together.

Fibrous root system: crabgrass

Answer 2

A fibrous root system (sometimes also called adventitious root system) is the opposite of a tap root system. It is usually formed by thin, moderately branching roots growing from the stem.

A fibrous root system is universal in monocotyledonous plants and ferns, and is also common in dicotyledonous plants.

Most trees begin life with a taproot, but after one to a few years change to a wide-spreading fibrous root system with mainly horizontal surface roots and only a few vertical, deep anchoring roots. A typical mature tree 30-50 m tall has a root system that extends horizontally in all directions as far as the tree is tall or more, but well over 95% of the roots are in the top 50 cm depth of soil.

A few plants with fibrous root systems:

Gabrielles
Pteridophyta
White clover (Trifolium repens)
Marigold
Weed

Answer 3

Fibrous roots are the most common type of roots.

(2) Fibrous root system
Synonym: Diffuse root system or Fasciculate root system

A fibrous (Also diffuse or fasciculate) root system is a kind of root system in which both primary and lateral roots are finely divided and have approximately equal diameters, without evident thickening or an enlarged central root.

Most monocots have a fibrous root system consisting of an extensive mass of similarly sized roots. In these plants, the radicle is short lived and is replaced by a mass of adventitious roots which are roots that form an organs other than roots; for example the stem. ( For example, the root of the grass )
