Document Summary
Microscopy: ratio between the size of an image produced by a microscope. Resolution (clarity: ability to observe two adjacent objects as distinct from one another. Light microscope: ability to distinguish different structures, can be enhanced using dyes, uses light for lamination, resolution of 0. 2 um, uses an electron beam (short wavelength, resolution 2nm, requires coating with heavy metal. Shows subcellular localization: nucleus blue, mitochondria orange, cytoskeleton green. All life can be placed into two categories: Cell structures as key organizing features: prokaryotes (bacteria, archaea, eukaryotes, the cell membrane is the border between cell exterior and its, the interior of the cell is called cytoplasm interior. Physical and biological principles that influence cell structure. All cells export macromolecules from their cytoplasm to outside the cell membrane: to form a protective matrix on the exterior side of the cell"s. Cytoplasm is an aqueous environment further organized into specific.
