Embryo- it is form from fertilized egg also called as zygote and produced due to fusion of sperm from germinated pollen and female egg. It consist of 4 parts epicotyl, hypocotyl, radicle and cotyledon. 2. Food storage- it is used for the germination of embryo. 3. Seed covering - it is the outermost covering of seed which protect seed from external environment and impermeable to water. Endosperm also the part of seed and have triploid chromosome component part and mainly occupy large part of seed. Zygote is the cell and form due to combination of genome and considered as initial stage of formation of seed. Sporophyte is the alteration of generation and responsible for production of gametophytes and sporophyte which is responsibleso for the production of sperm. Pollen is also regarded as pollen grains and carry male gametophytes fir further fusion. Fruit it is outermost part and covering of seed. Hence pollen , sporophyte and zygote is the initial stage of development whereas seed cover and endosperm are the parts of seed and fruit is last one for formation after seed..
