Totipotent cells meaning
WebThe ability of an isolated cell to develop into a fertile adult is proof of totipotency in this sense. As a result, a totipotent cell is also a one-cell embryo, meaning it is able to produce a developmentally coordinated sequence at the global level. E.g. zygotes, spores, etc.
