Morula

Definition

A morula is an early stage in embryonic development that consists of a solid ball of cells resulting from the division of a fertilized ovum. It forms before the blastocyst stage and after the zygote stage.

Zygote: A zygote is the initial cell formed when a new organism is produced by sexual reproduction, created when an egg cell is fertilized by a sperm cell.

Blastocyst: A blastocyst is the stage in embryonic development that follows the morula, characterized by a fluid-filled cavity and differentiation into an inner cell mass and outer cells.

Embryogenesis: Embryogenesis is the process by which the embryo forms and develops, starting from fertilization through stages like the morula and blastocyst, leading to further differentiation into tissues and organs
