What are cotyledons also known as?

Options

Answer 1

Cotyledons are embryonic leaves commonly called seed leaves. They are present in the embryo and differ in number between monocots (one cotyledon called scutellum) and dicots (two cotyledons). In dicots, cotyledons store food material; in monocots, the endosperm stores food which the scutellum absorbs.
