Morphology

phytohormone = hormone (transparent) = phyto + hormone

The word is transparently constructed from 'phyto' (plant) and 'hormone', indicating a plant hormone.

Etymology

The word phytohormone combines phyto- meaning 'plant' and hormone, a word for a chemical that 'urges' or 'moves' processes in a living thing. So a phytohormone is a plant's own chemical messenger that tells it when to grow, make roots, or ripen fruit.
