Question

Size or magnification: By knowing the size or magnification, you can often determine are looking at the structure of a tissue or the ultrastructure inside of a cell. An oval sha structure could be an entire cell or just the nucleus, so knowing something about the size of you are looking for can be helpful. Look at the 3 examples provided. Use what you know abour tne size oft cells and organelles and the information provided on the photomic whether you magnification or a bar indicating the size scate) to help you determine what you are seeing 4. In Figure A, how large is one triphasic granule? 5. In Figure B, what is the diameter of the peripheral airway shown? 6. Calculate the actual magnification of these two photomicrographs (Fig A & B). Show your calculations and explain your reasoning. 7. In Figure C, the magnification of the respiratory mucosa shown is 2500X (Top) and 3000X (Bottom). What structures can you see at this magnification? have provided you an opportunity to compare different types of different with different types of microscopy what you see-D imagewill differ depending on which plane was sectioned. Figure Method: Exercises above microscopy. Not only is the possible magnification is different. For example, in scanning electron microscopy you are viewing a surface rent in transmission electron microscopy you are viewing a cross-section and you get structures and the ara several ways of viewing cells: a schematic, light microscopy, D is provided for you to compare several transmission electron microscopy, scanning electron freeze fraction electron microscopy, expect to be able to see nuclei? Secretory granules? Briefly explain. able to 8. In which view do you

Explanation / Answer

Answer 4) Based on the scale provided in the Figure A., the size of one triphasic granule is 1m.

Answer 7.) The First figure with 2500X magnification shows only the surface of a bunch of Goblet cells and the cilia cover on the surface. The second figure with 3000X magnification shows the surface of singular goblet cells alongwith a few cilia and mucous present on the surface.
