Either of two nuclei located centrally in a flowering plant embryo sac that eventually fuse to form the endosperm nucleus. A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. The nucleus of a megasporocyte, a diploid cell that undergoes meiosis to produce four megaspores, and its descendents.
