3.  Eukaryotic cells are highly organized structures which are made up of smaller structures called organelles.  Some of these structures include: nucleus, cytoplasm, lysosomes, centrioles, mitochondrion, chromosomes, endoplasmic reticulum, Golgi apparatus, cell membrane, and nucleolus.  Use the drawing on your paper to identify each structure and tell its function (What does it do in the cell?).
