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)
