NEET 2020 · BiologyRoot typesPrevious Year Question
The roots that originate from the base of the stem are:
Answer: (C) Fibrous roots. In monocotyledonous plants (e.g., wheat) the primary root is short-lived and is replaced by a large number of roots that arise from the base of the stem; these constitute the fibrous root system.
- A.Prop roots
- B.Lateral roots
- C.Fibrous roots✓
- D.Primary roots
Correct Answer
(C) Fibrous roots
Solution & Explanation
In monocotyledonous plants (e.g., wheat) the primary root is short-lived and is replaced by a large number of roots that arise from the base of the stem; these constitute the fibrous root system. Hence roots originating from the base of the stem are fibrous roots. NCERT Reference: Ch 5, p.58, lines 32-34 — "These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant"
