Root Explanation

Hypocotyl is formed from "hypo-" (meaning under) and "cotyl" (from Greek "kotyle", meaning cup or hollow). The term refers to the part of a seedling that is located below the cotyledons, essentially the stem that is under the seed leaves.

Memory Tip

Think of 'under' ('hypo-') and a 'cup' or 'hollow' ('cotyl') to remember that a hypocotyl is the part of a seedling that is beneath the seed leaves.
