The embryo begins to form through a process called embryogenesis, which starts with fertilization of an egg by a sperm. The zygote (fertilized egg) undergoes cleavage, forming a solid ball of cells called a morula, which then develops into a hollow ball of cells known as a blastocyst. The blastocyst then implants into the uterus, initiating further development of different germ layers and body structures.
