Answer 2

Endosperm is the name of food laden tissue which is meant for nourishing the embryo in seed plants.

In gymnosperms it represents the female gametophyte. In angiosperms the endosperm is a special tissue which is formed as a result of vegetative fertilization, triple fusion or fusion of a male gamete with diploid secondary nucleus of the central cell. The fusion product is primary endosperm cell having a triploid endosperm nucleus.

Depending upon the mode of its formation, angiospermic endosperm is of three types— nuclear, cellular and helobial.
