The primary functions of the nucleus are to store the cellâs DNA, maintain its integrity, and facilitate its transcription and replication. The main function of the nucleus is to control cell activities and carry genetic information to pass to the next generation. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. The fertilization of the central cell produces the endosperm, a specific organ that serves as an interface for resource transfer between the diploid mother and its offspring (like the placenta in mammals). Its main function is to regulate gene expression; it also controls cellular growth and replication.
