BSCI105, Section 0111 Summer 2010 Study Guide #3 I. Structure and Function of the Cell Vocabulary: Prokaryote Eukaryote Plasma membrane Lipid bilayer Cytoplasm/cytosol Chromosome Ribosome Nucleoid Nucleus Cell wall Flagella Cilia Endomembrane Cytoskeleton Nuclear envelope Nuclear pore Nuclear lamina Nucleolus Chromatin Histone rRNA Endoplasmic reticulum (ER) Golgi lumen cis- trans- Cisternae Endosome Vesicle Vacuole Lysosome Mitochondria Chloroplast Peroxisome Microtubule Microfilament Tubulin Actin Intermediate filament Keratin Centrosome Extracellular Matrix (ECM) Collagen Proteoglycans Fibronectin Integrins Cell junction Plasmodesmata Tight junction Desmosome Gap junctions Key Concept 1: All living organisms are made from cells that belong to two major groups, the prokaryotes and eukaryotes, which differ in the presence of endomembranes. Key Concept 2: All cells have a limiting plasma membrane containing cytoplasm with DNA, RNA, and ribosomes. Key Concept 3: Prokaryotic cells lack endomembranes or a cytoskeleton, in contrast to eukaryotic cells use membrane bound organelles and a cytoskeleton to compartmentalize cell functions. Key Concept 4: The cell nucleus consists of a double membrane envelope with large pores supported by the nuclear lamina that contains DNA complexed with proteins (chromatin). Key Concept 5: The nucleolus is a dense body in the nucleus that is the site of rRNA synthesis
