Morphology
gastrulation = gastrula (semi-transparent) = gastr + ula + tion
The word is built in the regular way from the technical base 'gastrula' plus '-tion', so the process noun is structurally clear if the base is known.
Etymology
Gastrulation comes from the root gastr- meaning 'stomach', the same root in gastric. It names the early process when an embryo's cells move inward to form the gut, so gastrulation is literally the making of a little 'stomach' or gut.
