fibrous roots
Explanation: 

Detailed explanation-1: -Thin, branched roots that arise from the base of the stem are known as fibrous roots. Grasses and monocotyledons are characterised by the presence of fibrous roots. The roots are moderately branched, but once a tree fully matures it gives a mat-like appearance. The thin roots have the same diameter.

Detailed explanation-2: -There are two types of root systems: taproots and fibrous roots (also known as adventitious roots; Figure 2.1. 2). Tap roots have a prominent primary root that develops when the seed germinates and the radicle emerges. From there, secondary or lateral roots grow.

Detailed explanation-3: -The roots that have no prominent central axis and that branch out in all directions are called fibrous roots.
