coleoptile

/kɒliːˈɒptɪl/ UK

Where it comes from

A classical compound of the Ancient Greek κολεός (koleós, “sheath”) + the English -ptile (“leaf”) – the suffix representing the Ancient Greek πτῐ́λον (ptĭ́lon) – probably after the French coléoptile.

noun coleoptiles

A pointed sheath that protects the emerging shoot in monocotyledons such as oats and grasses. This kinetic scheme was proposed to account for the observed responses of Avena coleoptiles, and it was thought that it could also be applied to the phototropic responses of corn coleoptiles.
