Root System Types in Dicots — NEET Biology
📚 Practice ConceptIn majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. It bears lateral roots of several orders that are referred to as secondary, tertiary, etc. roots. The primary roots and its branches constitute the
Which of the above statements are correct? S1: Roots generally exhibit negative phototropism, guiding their growth away from light sources. S2: The region of meristematic activity in the root is primarily characterised by cells undergoing rapid elongation and enlargement. S3: The main function of the root cap is the efficient absorption of water and minerals from the soil. S4: Lateral roots within a taproot system are commonly referred to as secondary and tertiary roots, branching from the primary root. S5: In monocotyledonous plants, the entire fibrous root system originates directly from the plumule of the embryo.
