Fibrous or adventitious root system is mostly found in monocot plants. The following are the characteristic features of these roots:

• This is the most common type of root system found in monocotyledonous plants and pteridophytes.

• In this type of root system, the radicle is short lived and gets degenerated after some time. Later a number of fiber-like new roots develop from the base of the stem.

• As these roots develop from parts of the plant other than radicle, this is called adventitious root system.

• A bunch of uniform roots arise from the base of the stem.

• These roots are slender, shallow and develop equally.

• All the roots look like fibers and hence the name fibrous roots.
