Structure
A nuclear membrane,
nucleoplasm, nucleolus,
and chromosomes make up
the nucleus. The
nucleoplasm is the matrix
that surrounds the nucleus.
The nuclear membrane is a
double membrane that
surrounds the entire

cytoplasm.
Function
Controls and regulates the cell's processes
(e.g., growth and metabolism), as well as
carrying the genes, which are structures that
contain hereditary information.
