2 All other forms of life are composed of more complex eukaryotic cells 4.4 Eukaryotic cells are partitioned into functional compartments Distinguished by the presence of a true nucleus − two types of organelles: membranous and nonmembranous

3 Membranes form the boundaries of many eukar yotic cells Compar tmentalizing the interior of the cell and facilitating a variety of metabolic activities Membranous organelles nucleus endoplasmic reticulum (E.R) Golgi apparatus mitochondria lysosomes peroxisomes Nonmembranous organelles ribosomes centrioles flagella cytoskeleton
