Question

In maize, the fibrous roots develop from

• A. Lower nodes
• B. Upper nodes
• C. Upper internodes
• D. None of the above

Answer 1

The correct option is A Lower nodes

Root is the portion of the main branch that goes into the soils and provides anchorage to the plant. Roots are of two types- taproots and fibrous roots. In fibrous roots, the primary root is short-lived but a cluster of slender, fiber-like roots arises that makes up the fibrous root system. This type of root system is found in most of the monocots. However, in maize, the fibrous roots is a nodal root system where the roots originate at one of the lower stem nodes of the plants. While the bulk of the root system grows from the 5 nodes below the soil surface, brace roots that grow from nodes present above the soil surface brace the plant from winds.

Therefore, the correct answer is option A.
