BIOS 242 Week 2 Assignment; Lab 3 of 14 Onsite; Microscopy Observation of Cells Lab 3: Microscopy- Observation of Cells Learning Objectives: Use the compound light microscope for observation of cells. Identify different types of bacteria based on their shapes. Identify a variety of eukaryotic cells. Introduction: Microbiology is the study of organisms, which cannot be seen with naked eye. You will need help of a microscope to observe these “tiny animalcules” as they w...

Biology 1406 Lab Exam 1 fully solved rated A+Why is oil immersion used? - correct answer To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? - correct answer Illuminator-The light source for the microscope. Diaphragm-Controls the amount of light entering the conde...
