●Magnification- image enlargement
●resolution/resolving power- shortest distance that two objects may be to each other and
still be seen as two objects
●Air-occupies the space between the objective lens and the coverslip on the slide
●Compound light microscope-in which light is transmitted through a specimen, specimen
has to be small, thin and relatively transparent in order to allow the light to go through,
provides an image that is two dimensional
●Total magnification in the compound light microscope is calculated by multiplying the
magnification of the ocular by the magnification of the object you are using
●Scanning objective- shortest objective
●Low power objective- next shortest objective
●High power objective- next shortest objective
●Oil immersion objective- longest objective
●The cell theory
○All living things are composed of one or more cells
○The chemical reactions of living cells take place within cells
○All cells originate from pre-existing cells
○Cells contain hereditary information, passed from one generation to other
●Eukaryotic cells- contain a membrane bound nucleus and membrane bound organelles,
plant and animal cells
○More complex than prokaryotic, believed to have evolved from them
○Animal cells are eukaryotic
■Usually have nucleus, cytoplasm and outer cell membrane
○Photoautotrophs- make their food through photosynthesis
○All are bound by a plasma membrane like prokaryotic cells but some are
additionally surrounded by a cell wall
■This is a plant cell animal cells do not have a cell wall
○Organelles - serve to subdivide the cell into different functional compartments
■examples :
●Nucleus- contains DNA in eukaryotic
●Mitochondria- responsible for ATP generation for cell activities
●Endoplasmic reticulum- site of most of the cells production of
proteins and other cell compounds
●Golgi bodies - packages proteins and lipids destined for export,
packages enzymes into lysosomes for cellular use
