Ques. 1NEET (UG) 2020
The roots that originate from the base of the stem are
- Primary roots
- Prop roots
- Lateral roots
- Fibrous roots
Answer
(4) Fibrous roots
Solution
As per NCERT, in monocotyledonous plants the primary root is short lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant.
Primary roots, by contrast, arise from the radicle and lateral roots arise from the primary root, while prop roots (e.g., banyan) arise from branches and hang down for support.
Roots originating from the base of the stem are fibrous roots.
