Options

A. A – Hilum, B – Micropyle, C – Plumule, D – Radicle, E – Cotyledon
B. A – Micropyle, B – Hilum, C – Plumule, D – Cotyledon, E – Radicle
C. A – Hilum, B – Micropyle, C – Plumule, D – Cotyledon, E – Radicle
D. A – Hilum, B – Micropyle, C – Radicle, D – Cotyledon, E – Plumule

Answer

C

Explanation

Hilum: The concave side of seed is slightly darker and posses a white elongated scar called hilum which marks the point of the attachment of the seed with funiculars. Micropyle: A small pore lies adjacent to the hilum called micropyle. Plumule: The side of embryonal axis lies in between the two cotyledons. It is plumule. Cotyledon: The reserve food material. Radicle: The micropylar end of embryonal axis is rod shaped and slightly bulged.
