Explanation

Endosperm is the most common nutritive tissue for the developing embryos in angiosperms. It is developed after fertilization by triple fusion i.e., by the fusion of two polar nuclei and second male gamete, therefore it is triploid. Family Orchidaceae, Podostemaceae and Trapaceae in angiosperms do not form endosperm. In gymnosperms the endosperm is formed before feritlization therefore it is haploid.
