FUTURE ROLE OF CELL
 Decided in the early development of an embryo.
 In the development, first stage is cleavage-mitosis cell divide
repeatedly
 Rerut of cleavage is mass of spherical cells, identical and
undifferentiated cells called blastocyst.
 Human process takes place in a week.
 Tiny cells at an embryo one called stem cells.
 Stem cell develops into specialized cells.
 In blastocyst outer layer from placenta.
 Inner cell said to be pluripotent.
 Totipotent in plants-cloning
 Totipotent in animal-embryo splitting
