Download Understanding Eukaryotic Cells: Functions, Compartments, and Protein Transport - Prof. Pau and more Study notes School management&administration in PDF only on Docsity! 14 October The major functions of eukaryotic cells Intracellular compartments – main difference with prokaryotes Cellular communication – signaling Cell shape and movement – cytoskeleton Cellular growth control – cell cycle Eukaryotic cells can engulf other cells by phagocytosis Rapid change of shape Mediated by the cytoskeleton Example: neutrophil engulfing a red blood cell Eukaryotic cells may have originated as predators The major intracellular compartments of a eukaryotic cell Eukaryotic cells have membrane enclosed organelles Provide more membrane and separate compartments for specialized functions Organelles have characteristic positions – interaction with cytoskeleton Evolution of the nucleus and the endoplasmic reticulum ER lumen is continuous with the space between inner and outer nuclear membranes Modern eukaryotic cells evolved from a symbiosis Mitochondria has its own DNA, ribosomes, and transfer RNA
