What is the total magnification of a sample imaged with a 60x objective and a 10x eyepiece? (short answer) - Answer 60 x 10 = 600x magnification True or False: A cell that is adherent, flat, and unstained is easily identified using bright field microscopy - Answer False. Adherent, flat cells are almost invisible due to the limits on both resolution and contrast Which of the following could be seen clearly by the unaided eye? (multiple choice) - Answer Protozoa with diameter of 150um ...
