which type of stem cells is able to differentiate into any cell type, including extraembryonic placental cells?

a embryonic cells
b totipotent cells
c multipotent cells
d pluripotent cells

1 answer

The correct answer is b) totipotent cells. Totipotent cells have the ability to differentiate into any cell type, including all embryonic and extraembryonic cell types, which means they can form an entire organism. Embryonic stem cells (typically considered pluripotent) can differentiate into almost all cell types but cannot form extraembryonic structures like the placenta.
