OBJECTIVES • Describe the function of the listed cellular components. – Nucleus • Chromatin • Nuclear envelope • Nuclear lamina • Nuclear pore complex – Endoplasmic reticulum (ER) • Rough • Smooth – Ribosome – Golgi apparatus – Lysosomes – Mitochondria – Describe the flow of molecular information from the nucleus to ER to Golgi to plasma membrane. Prokaryote vs. Eukaryote • Prokaryote - A simple, unicellular organism, such as a bacterium, that lacks a discrete nucleus surrounded by a nuclear membrane, and that contains its genetic material with in a single chromosome. • Eukaryote - A higher organism (unicellular or multicellular) that consists of cells that possess a true nucleus; the nucleus is surrounded by a nuclear membrane and contains the genetic material within multiple chromosomes. Contains an ER. A prokaryotic cell Contains no ER Cytoplasm vs. Cytosol • Cytoplasm - The entire contents of a cell, exclusive of the nucleus, and bounded by the plasma membrane.plasma membrane....
