Parts of the Seed - MyCAERT
www.mycaert.comThe mature embryo consists of an embryonic root known as the radicle, an embryonic shoot, and one or two cotyledons. The embryonic shoot, known as the plumule, has two main parts, the epicotyl and the hypocotyl. The epicotyl is the portion of the embryonic stem above the point at which the stem is attached to the cotyledon(s). The hypocotyl is ...

INTRODUCTION TO HUMAN DEVELOPMENT
www.columbia.eduEmbryo: This term refers to the developing human during the early stages of development. The term is usually not used until the 2nd week, when a bilaminar (two layered) embryonic disc is formed. The embryonic period extends until the end of the eighth week, by which time all major structures and organs have formed.
