Question

Primary root structure grows from the elongation of __________

• A. Lateral root
• B. Plumule
• C. Radicle
• D. Tap root

Answer 1

The correct option is C

Radicle

Primary root grows from the elongation of radicle and is considered as the first root of a plant, originating in the embryo. In gymnosperm, the primary root develops into the taproot while in monocot plants this primary root disintegrates as the lateral roots develop into a system of fibrous roots.
