Question

Identify the labelled parts in the given figure of a dicot embryo.

• A. (i)-Plumule, (ii)-Cotyledons, (iii)-Hypocotyl, (iv)-Radicle, (v)-Root cap
• B. (i)-Plumule, (ii)-Cotyledons, (iii)-Radicle, (iv)-Hypocotyl, (v)-Root cap
• C. (i)-Stem tip, (ii)-Cotyledons,(iii)-Hypocotyl, (iv)-Root cap, (v)-Root tip
• D. (i)-Stem tip, (ii)-Cotyledons, (iii)-Root tip, (iv)-Hypocotyl, (v)-Root cap

Answer 1

The correct option is A

(i)-Plumule, (ii)-Cotyledons, (iii)-Hypocotyl, (iv)-Radicle, (v)-Root cap

A dicot embryo consists of two cotyledons and an embryonic axis. The region above the cotyledons is called epicotyl which terminates at the plumule. Hypocotyl is the region below the cotyledons and terminates at the radicle. The tip of the radicle is covered with a root cap.
