- magnification in a compound light microscope.
- The magnification in a compound light microscope is the increase in apparent size of an object.
- Resolving power in a compound light microscope
- The resolving power in a compound light microscope is the measure of clarity of an image
- Structures of a compound light microscope.
- The compound light microscope consists of an eyepiece, ocular lenses, objective lenses, condenser lens, and a light source.
- Finding total magnification
- Power of ocular lens (eyepiece) X Power of objective lens
- Finding Field of View (FOV)
- Total magnification of medium power / total mag of low = X
- Convert mm to microns
- 1mm = 100 microns 1 micron = 1/100 mm 1 micron = 0.001 mm X(1000) = size of specimen
- Function of a light compound light microscope.
- The light compound microscope bends the light to magnify the image of a specimen and project the image into the viewer's eye or onto a photographic film.
- The volume of a cell and its ability to obtain nutrients
- The larger the surface area the more nutrients it can hold. It doesnt dictate size. Only surface area : Volume ratio.
- Compare and Contrast the structures of a prokaryotic and a eukaryotic cell.
- Prokaryotic are a lot smaller and take more magnification to see anything on it while eukaryotic are a bit larger and you can identify organelles at less magnification.
- Compare and contrast the smooth and rough ER
- The smooth ER doesn't have any ribosomes attached to it whereas rough ER does. They both move substances within cells.
- The role and origin of a lysosome.
- - The role of a lysosome is to aid in cell renewal, break down old cell parts, and digest invaders. - The origin of a lysosome is the golgi apparatus and rough ER.
