Roots developed from parts of the plant other than radicle are called
(a) Tap roots (b) fibrous roots (c) adventitious roots (d) nodular roots
Roots developed from parts of the plant other than radicle are called adventitious roots. They branch like tap roots and may be underground or aerial, and may develop from nodes internodes on leaves, etc.
Other options are incorrect because
Tap roots are the roots developed form the radicle of embryo and persists and grows directly into primary root.
Fibrous roots are thin, thread-like branched roots developing from base of stem. These are modifications of tap root, found in monocots.
Nodular roots are also modifications of tap roots in which roots and its branches develop small or large swalling called nodules. They help in nitrogen fixation.
