Germ cell
A
germ cell
is any
biological cell
that gives rise to the
gametes
of an organism that
reproduces sexually
. In many animals, the germ cells originate in the
primitive streak
and migrate via the
gut
of an
embryo
to the developing
gonads
. There, they undergo
meiosis
, followed by
cellular differentiation
into mature gametes, either
eggs
or
sperm
. Unlike animals,
plants
do not have germ cells set aside from in early development. Instead, germ cells can come from
somatic cells
in the adult (such as the floral
meristem
of flowering plants).
