Nucleus. The cells of animals and plants almost always have a ‘true’ nucleus. A nucleus consists of a nuclear envelope, chromatin, and a nucleolus. The nuclear envelope is made from two membranes and encapsulates the contents of the nucleus. The double membrane has numerous pores to allow substances to move in and out of the nucleus.
