DEFINITION : Morula, solid mass of blastomeres resulting from a number of cleavages of a zygote, or fertilized egg. Its name derives from its resemblance to a mulberry (Latin: morum). A morula is usually produced in those species the eggs of which contain little yolk and, consequently, undergo complete cleavage. • DEFINITION 2 : An early stage in post-fertilization development when cells have rapidly mitotically divided to produce a solid mass of cells (12-16 cells) with a mulberry appearance. This stage is followed by formation of a cavity in this cellular mass blastocyst stage • STAGES : 1 Fertilization and the zygote · 2 Cleavage and morula · 3 Formation of the blastula · 4 Formation of the gastrula. • 00:00 Topic • Morula vs Blastomere 3:06 : The two-cell blastomere state, present after the zygote first divides, is considered the earliest mitotic product of the fertilized oocyte. When the zygote contains 16 to 32 blastomeres it is referred to as a morula. These are the preliminary stages in the embryo beginning to form. • #Morula
