Detailed explanation-1: -The zygote begins to divide via mitosis after fertilization. The solid ball of cells known as a morula is made up of 8-16 blastomeres . It then divides and differentiates further to form a hollow ball known as a blastocyst.

Detailed explanation-2: -A morula is an early-stage embryo consisting of 16 cells (called blastomeres) in a solid ball contained within the zona pellucida. The morula is produced by a series of cleavage divisions of the early embryo, starting with the single-celled zygote.

Detailed explanation-3: -A zygote undergoes rapid cell divisions (cleavage) to form a spherical ball of cells: the blastula; this will further develop into a blastocyst.

Detailed explanation-4: -A morula (Latin, morus: mulberry) is an early-stage embryo consisting of a solid ball of cells called blastomeres, contained in mammals, and other animals within the zona pellucida shell.

Detailed explanation-5: -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.
