A seed is a precursor of new plant growth as it enclosed in itself the plant embryo after the process of fertilization of the male gamete pollen with the female gamete egg. The formation of seed is a characteristic feature of spermatophytes like gymnosperms and angiosperms. A seed typically composed of necessary nutrients which will sustain the young embryo and helps in the germination process. The hard protective coating prevents the loss of water from the seed so as to sustain the young embryo until it get germinated.
