Explanation:
Totipotent cells are those cells in developmental stage of multicellular organisms which can give rise to any part of the organism. It can give rise to both the placenta and the embryo.
After the fertilization, the cells produced in first few divisions are totipotent. This stage is also called as morulla stage. Once blastocyst stage is reached, totipotency is lost. All the cells of blastocyst are not totipotent. The inner cell mass of blastocyst is pluripotent which means it can give rise to the entire embryo except placenta. The trophoblast layer of blastocyst can only produce placenta.
