In the embryos of a typical dicot and a grass, true homologous structures are

Options

A. Coleorhiza and coleoptile
B. Coleoptile and scutellum
C. Cotyledons and scutellum
D. Hypocotyl and radicle.

Answer

C

Explanation

A typical dicotyledonous embryo consists of two cotyledons. While, embryos of monocotyledons possess only one cotyledon and it is called scutellum (in grass). Cotyledons of dicots, are simple structures generally thick and swollen due to storage of food reserves (as in legumes) and embryo of monocots consists of one large and shield shaped cotyledon known as scutellum situated towards one side (lateral) of the embryonal axis.
