The section of a young plant that connects the root to the stem, located below the seed leaves.
The hypocotyl is crucial for the growth of the seedling as it helps support the plant above the ground.
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.
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.
