Question

Diagram represents L. S. of monocot seed. Find out correct combination of labelling.

• A. a - aleurone layer, b - scutellum, c - coleoptile, d - coleorhiza
• B. a - seed coat, b - scutellum, c - coleoptile, d - coleorhiza
• C. a - epithlium, b - scutellum, c - coleoptile, d - coleorhiza
• D. a - endosperm, b - scutellum, c - coleoptile, d - coleorhiza
• E. a - endosperm, b - scutellum, c - plumule , d - radicle

Answer 1

The correct option is D a - endosperm, b - scutellum, c - coleoptile, d - coleorhiza

A. Endosperm- In monocot endosperm provide food material to the developing embryo.

B. Scutellum- Embryo consists of a upper shield shaped called scutellum which is a reduced cotyledon.

C. Coleoptile- It is a protective sheath of plumule in monocots.

D. Coleorhiza- It is a protective sheath of radicle in monocots.

So, the correct answer is 'a- endosperm, b- scutellum, c- coleoptile, d- coleorhiza'.
