A seed is a little embryonic plant encased encased in a covering called the seed coat, for the most part with some stored food. It is the result of aged ovule of gymnosperms and angiosperms plants which happen after preparation and some development inside mother plant.

An embryo is a multicellular diploid eukaryote in its soonest phase of improvement, from the season of first cell division until birth, incubating and germination. In people, it is called a developing life until around two months after mating and that is called embryo.
