BIOL 102 Lecture Notes - Lecture 3: Transmission Electron Microscopy, Scanning Electron Microscope, Cell Theory
Document Summary
Sem : scanning electron microscope surface magnification (requires metal coating) Difference between prokaryotes and eukaryotes is the organization of the cell. Lack of cell wall causes the cell to be susceptible to expanding/shrinking, therefore internal salt levels must be sustained. Plant cell: lack of lysosomes, contain plastids: ex chloroplasts. Proteome determines the characteristics of a cell controlled by the genome (genome never changes) determines structure and function of a cell. Cytosol: the liquid surrounding the organelles inside the plasma membrane. Cytoskeleton: framework made of microtubules, intermediate filaments, and actin filaments.
