Answer:
A. Compound Light microscopes are the most commonly used light microscope. They can be found in most science classrooms and biology laboratories. The light source is below the stage, and the light shines through the thin specimen and the magnification lenses.
Functions: used to view tissue samples, blood, microorganisms in pond water, microscopic cells, and some of the larger details within the cells.
B. Dissecting Microscope is one type of light microscope. It is used for examining organisms at relatively low power, magnifying the image up to 40 times the size of the specimen.
Function: examining organs and tissue during dissection.
A.Scanning electron microscopes (SEM) are helpful for studying the details of a specimen’s surface. The electron beam scans the specimen’s surface, which is coated with a thin layer of gold metal.
Functions: forming a detailed image of the specimen surface.
B. Transmission electron microscopes (TEM) pass a beam of electrons through a thin specimen similar to how a compound light microscope transmits light. Scientists can apply stains to the specimen to increase contrast in the image.
Functions: mainly used for studying the internal structures of cells that cannot be viewed under light microscopes.
