The Nucleus is the largest organelle, features include:- Nuclear Envelope - two membranes with fluid
between them
- Nuclear Pores - holes that go right through the
envelope
- This allows relative large molecules to pass
through
- Nucleolus - a dense, spherical structure
The nucleus contains almost all of the cell's genetic material. The DNA contains instructions for making proteins. Some of these proteins regulate cell activity.
The nucleus also makes RNA and Ribosomes
