A student was viewing a prepared slide of a plant cell under high power microscope. The features of the cell were blurred. Which one of the labeled parts of the microscope would the student use to obtain a sharper outline of the features.

a) The student's answer is correct. To obtain a sharper outline of the features when viewing under high power, the student would use the fine adjustment knob. b) The formula used to calculate magnification in a light microscope is: Total Magnification = Magnification of Eyepiece Lens × Magnification of Objective Lens So, the formula is: Total Magnification = Eyepiece Magnification × Objective Magnification c) i) Cutting a very thin section: This is done to allow light to pass through the specimen, making it transparent enough for observation under the microscope. ii) Staining the section: Staining is done to add color to specific cell structures (like the nucleus or cytoplasm), making them more visible and distinguishable from each other. iii) Putting the section in water: This step is taken to prevent the specimen from drying out and to keep it flat, which helps maintain its natural structure and allows for clear viewing. 3 done, 2 left today.
