The Cell Nucleus: The cell nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is the command center of a eukaryotic cell and is commonly the most prominent organelle in a cell.Distinguishing Characteristics:he cell nucleus is only one type of cell organelle. The following cell structures can also be found in a typical animal eukaryotic cell: 1  Centrioles-help to organize the assembly of microtubules. 2  Chromosomes-house cellular DNA. 3  Cilia and Flagella-aid in cellular locomotion.
