noun, plural morulas, morulae. [mawr-oo-lee, -yoo-] /ËmÉr ÊËli, -yÊ-/ (Show IPA). Embryology. 1. the mass of cells resulting from the cleavage of the ovum before the formation of a blastula. Origin of morula.
A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. The events during the zygote stage involve the integration of both parents' DNA into the cell nucleus and the beginning of rapid cell division, or cleavage. In humans, it takes about four days for a zygote to become a morula and another three days until the embryo attaches itself to the motherâs uterine wall.
