Question

Which of the following structures is unique to the seed of a monocot?

• A. Coleoptiles
• B. Radicle
• C. Seed coat
• D. Endosperm

Answer 1

The correct option is A Coleoptiles

A monocotyledonous seed is the one which has a thick seed coat. Inside the seed coat are the endosperm and the embryo. Endosperm is the nourishing tissue which provides food for the growing embryo.In monocots, single cotyledon present is called as scutellum which absorbs nourishment from the endosperm and transfers to the growing embryo. The embryo has two structures namely, radicle and plumule. Radicle, the future root is protected by a sheath called as coleorhiza and plumule, the future shoot is protected by a sheath called as coleoptile.

So the correct option is 'coleoptiles'.
