![]() Pluripotent cells can generate any of the cell types that make up the body pluripotent are called embryonic stem cells. The only totipotent cells are the embryonic cells inside the first couple of cell divisions after fertilisation. ![]() Totipotent cells can form all types of cells in a body, including the cells that are extraembryonic, or placental. ![]() So the correct answer is the option ‘A’ “An undifferentiated cell capable of developing into a system or entire plant.” It differentiates into the different vegetative plant after stem formation. When treated with auxin, the callus promotes rooting and when treated with cytokine it stimulates cell maturation, differentiation and ultimately promotes stem growth. The totipotent cells have enormous cytoplasm and an active nucleus that allows for the rapid division.įor example, the growth hormones are handled with a callus to enable cell division and differentiation. ![]() Tarkowski (1959)2 conducted the original totipotency test in mice, which isolated a single blastomere (cells produced by divisions of the zygote, consisting of 2–16 cells) and placed it in an empty zone pellucid, and tracked its development into live-born youth.Ī totipotent cell refers to an undifferentiated cell which can grow into a system or a whole plant. Hint: Stem cells are characterised by their degree of viability, which relates to their differing ability to differentiate into various types of cells and developing into a new system.Ī totipotent cell is a single cell, which provides proper maternal support, and can give rise to a new organism. ![]()
