Hypocotyl
Hypocotyl
The Hypocotyl (pronounced: hi-POH-ko-til) is a significant part of a plant's anatomy, specifically in the domain of embryonic development.
Etymology
The term "Hypocotyl" is derived from the Greek words "hypo" meaning under and "kotyledon" meaning a cup-shaped hollow.
Definition
The Hypocotyl is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (embryonic root).
Function
In dicot plants, the hypocotyl is the primary source of elevation for the cotyledon, lifting it above the ground. In some monocot (specifically grasses), the hypocotyl remains underground, and the cotyledon is not elevated.
