hers a happy answer to ur question :-)
The fertilised egg begins to divide inside the ovule and developed into an EMBRYO . The ovule develops into a seed . Besides the embryo , a seed also has ONE or TWO COTYLEDONS . The outer covering of a seed is called the SEED COAT .
The embryo has a RADICLE and a PLUMULE . It is attached to one or two cotyledons . open germination , the radical will develop into root system , while the plumule will develop into shoot system . The cotyledons have a store of food which is used by the SEEDLING .
FRUIT :-
In most plants the fruit begins to form only after the egg cells have fertilised . after fertilisation , the ovary begins to grow in size . The outer wall of ovary become thik and form the fruit . the petals and the stamens dry and fall off . who is the seed inside the ovary has fully developed the fruit ripens .
the fully form seed has an embryo . The Shield lost his most of water as he tries and becomes hard and strong . the heart should protect the embryo . most seed germinate only if they have dried .
