Q- In the embryos of a typical dicot and a grass, true homologous structuresare:a. Coleorhiza and coleoptileb. Coleoptile and scutellumc. Cotyledons and scutellumd. Hypocotyl and radicle
Among the given choices, in the embryos of a typical dicot and a grass, true homologous structures are cotyledons and scutellum. This is because scutellum is also cotyledon of monocot seeds. It is a single cotyledon found in monocot seeds and occupies the major portion of embryo. Cotyledon are the part of embryo, that serve as nutritive tissue for developing embryo. Cotyledons found in dicot seeds are two while only single cotyledon is found in monocot seeds which is known as scutellum.
