AI overview
An embryo is the earliest stage of development in a multicellular organism, beginning right after a sperm cell fertilizes an egg cell in sexually reproducing species. The fertilized egg then divides repeatedly, eventually forming a structured ball of cells with a fluid-filled cavity, which marks the transition into more complex development.
