Bio 150 – Laboratory #6 Report Human Anatomy & Physiology I DCCC Lab Report # 6 - Microscopy, Cells, and Mitosis Name: Kyrsten Paoli I. The Microscope 1. Which objective provides the largest field of view? 4X 2. What is the function of the stage? Holds/supports the specimen. Brings specimen to focus. 3. What is the magnification of the ocular lens? 10X 4. Which objective lens should be put in place prior to placing the microscope back in its storage compartment? 4X 5. Why is focusing done with the fine focus knob only when using the 10X, 40X, or 100X objectives? You can run the slide into the objective lens damaging or cracking the slide 6. Give the total magnification obtained when using the low power (10X) objective? 100X II. Cell Cycle & Mitosis B. Prepared slide of mitosis in Whitefish blastula Interphase 1.
