Stem cell[L. cella - compartment]. An undifferentiated
cell that is mitotically active in either replacing dying body
cells (
somatic stem cell) or producing
gametes (germinal
stem cell).
Full article >>>Stem cells are
cells that divide by
mitosis to form either
two
stem cells, thus increasing the size of the
stem cell "pool",
or
one daughter that goes on to differentiate, and
one daughter that retains its
stem-
cell properties.

cells that retain the ability to divide and differentiate into other
cell types. In higher
plants this function is the defining property of the
meristematic
cells.

stem cells are undifferentiated
cells that reproduce daily to provide certain specialized
cells-for example 200 billion
