Cell Parts and Functions

Cell Membrane

Protects the cell

Lets things in and out of the cell

Location: around the cell

• Nucleus Control center of cell

Double membrane

Contains - Chromosomes

-Nucleolus

Cell Parts and FunctionsNucleolus (Nucleoli)Makes ribosomeLocation: inside the nucleus (dark spot)
