station and seed formation to understand
the process of pollination we should
first know the anatomy of an overview of
fuel is a small structure contained in
the ovary each of you Liz attached to
the placenta buy a stock called the few
nickel which provides nourishment to the
ovule further of you Lissa rounded by to
protective coats called integuments
bearing a small opening at one end known
as a micro fight and if you see the
detailed structure of the ovule you will
find a small structure called an embryo
sac which contains an egg towards the
micropyle and also contains two polar
nuclei which are located in the center
moving down in the process after the
pollen grains are deposited on the
stigma the pollen grains absorb water
and sugar from the surface of stigma and
swell up to produce a pollen tube this
pollen tube eventually travels down the
length of the style into the ovary now
the two male gametes in the pollen tube
enter the ovule and fuse there with an
egg and polar nuclei
