Document Summary
Prokaryotic cell (no nucleus) include bacteria and are structurally simpler. Lecture 14 basic cell structure and diversity: microvilli are kept erect by a skeleton (actine) Prokaryotic cell include bacteria and are structurally simpler. Eukaryotic protists, fungi, plants, animals, structurally more complex: contains compartments which are membrane bound structures dedicated to a particular function, components are not bound by membranes. Cells : contain a large number of parts, organized with respect to time and space, parts interact with little tolerance for error, conserved through evolution. Cytoskeletal elements: actin filaments, microtubules, intermediate filaments, contribute to cell shape and movement, provide structural support, support transport of material, nuclear pore complex enables movement of molecules in ad out of the nucleus. Virus life cycle: proteins on the outside of the virus which interacts with the plasma membrane, what nucleic acid makes up this viral genome (doesn"t need to go into nucleus)
