Morphology
micropyle = micro + pyle
The word is technically compositional as micro- plus the Greek combining form pyle ('opening'), but pyle is not a productive everyday English morpheme, so the meaning is only partly transparent.
Etymology
The word micropyle comes from the Greek parts micro- 'small' and pyle 'gate'. So a micropyle is like a 'tiny gate' in the ovule where the pollen tube can enter, which explains its role in plant fertilization.
