The Nucleus
Nucleus
The nucleus is located in the cytoplasm of both plant and animal cells, usually around the central area.
It is enclosed by a double membrane called the nuclear envolope with small holes covering it called nuclear pores.
The nucleus is the control center for the cell and keeps the, highly important, chromosomes protected.

Nucleolus
The nucleolus is located inside the nucleus.
It is not membrane bound and is a very dense region of the nucleus made out of DNA, RNA, and proteins.
Its function is to make the small and large ribosome subunits for the cell.

Nuclear Membrane and Nuclear Pores

The nuclear envolope is located on the outside of the nucleus and is made of two layers of phospholipids with pores covering the membrane and allows the cell to have a different chemicle environments than the cytoplasm it is sitting in.
The nuclear pores covering the membrane are what control what gets in or out of the cell.

Chromosomes and Chromatin

The chromosomes in the nucleus are a double helix of nucleotides. It is made of chromotin wrapped around proteins that form the x shape.
Chromotin is unwound DNA that forms the chromosomes.
