In Biology the nucleus of a cell is the control centre, inside the nucleus is DNA which gives it the structure and knowledge to be what it is.
The small dot-like structure inside the nucleus is the nucleolus. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus is not surrounded by a membrane and can often be seen as a distinct structure within the nucleus.
the nucleus is surrounded by electrons, protons and neutrons. Inside the nucleus are quarks. (for the nucleus in an atom only)

A cell nucleus would be smaller than a cell because a cell nucleus is inside the cell, so it has to fit inside.
A Nucleus; inside of a cell; inside of a plant or animal cell; inside of a plant or animal; you can take it from ther. :) :)
