The nucleus of an antipodal cell, one of three cells of the embryo sac in angiosperms, found at the chalazal end of the embryo away from the point of entry of the pollen tube, and its descendents. Either of two nuclei located centrally in a flowering plant embryo sac that eventually fuse to form the endosperm nucleus. The nucleus of a plant egg cell. This nucleus is found at the micropylar end of the embryo. 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. Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
