endosperm

endosperm A nutritive tissue, characteristic of flowering plants, that surrounds the developing embryo in a seed. It develops from nuclei in the embryo sac and its cells are triploid. In endospermic seeds it remains and increases in size; in nonendospermic seeds it disappears as the food is absorbed by the embryo, particularly the cotyledons. Many plants with endospermic seeds, such as cereals and oil crops, are cultivated for the rich food reserves in the endosperm.

endosperm

endosperm Tissue that surrounds the developing embryo of a seed and provides food for growth. It is triploid (each cell has three sets of chromosomes), being derived from the fusion of one of the male gametes from the germinated pollen grain and two of the haploid nuclei in the embryo sac. See also alternation of generations
