Detailed explanation-1: -Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.

Detailed explanation-2: -Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.
