The fertilized egg is called what?

Explanation:
Fertilization creates a zygote, the single diploid cell formed when sperm and egg fuse. This zygote is the very first stage of development before any cell division has produced a multicellular structure. As development proceeds, it becomes a morula (a solid ball of cells) and then a blastocyst (a hollow ball with an inner cell mass), with the organism generally called an embryo after implantation. So the fertilized egg is specifically the zygote, while the other terms describe later steps in early development.
