Rio Salado BIO101 lab 3 part 2




Question;1. What type of microscope would be used in;the laboratory to observe very small objects or organisms on a slide? Please;give reasoning behind the answer. Which microscope would be useful when;studying the internal structure of a minute specimen? (2 points)--Answer below;2 List two jobs where microscopes are used.;Describe in what capacity.;3. Why is special paper used to clean the;lenses of a microscope?;4. State the name of each of the tagged;parts on the microscope shown above.;5. What type of microscope has primarily;been used in this lab;6 State the function of the following parts;of the microscope: (3 points) A. iris diaphragm B. ocular lens C. condenser;State how to adjust each of the following;components of the microscope (2 points);A. diopter B. interpupillary distance;8 What is the total magnification when;using a compound light microscope with an objective lens of 10X and an ocular;lens of 4X? Show the calculation used to derive the answer.;9. Why are coverslips used to observe;specimens under the microscope?;10 Letter ?e? exercise: A. Describe what;happens to a letter ?e? when placed under the microscope. How does this compare;to its appearance in the newspaper? (2 points) B. If the slide is moved to the;right with the mechanical stage, what direction does the specimen move while;observing it under the microscope?;1 10X. With the 10X magnified it made the;specimen close enough to see the colors the 40X over magnified the slide.;12.;What differences did the student observe in the various tissues/organelles of;the stained, prepared slides? (2 points)?;13. Why don?t all cells demonstrate the;presence of all intracellular structures? (3 points) --Answer below;14. Describe what the student sees as some;major differences between cells from the kingdom Plantae and Animalia. Propose;some reasons why these anatomical differences may exist. (5 points)--Answer;below;15. (Application) How might the information;gained from this lab pertaining to the microscopes be useful to the student, or;how can the student apply this knowledge to everyday life as a non-scientist?
