In the 1980s,biologists fused a mammary cell of an adult sheep into an enucleated,unfertilized egg of a second sheep and treated it with chemicals,causing it to grow into an embryo.After implantation in the uterus of a third sheep,the embryo grew to become a fully complete baby lamb.What term best describes the growth potential of that fused mammary cell and enucleated egg?

Totipotent cells have the ability to give rise to all cell types, including both embryonic and extraembryonic tissues, and can grow into a fully functional organism. The fused mammary cell and enucleated egg in this experiment were able to grow into an entire organism, indicating their totipotency. Pluripotent cells can develop into all cell types except for extraembryonic tissues, while multipotent cells can differentiate into a limited range of cell types. Unipotent cells can only give rise to one cell type.
