Test Bank for Essential Cell Biology 5th Edition Alberts Hopkin ESSENTIAL CELL BIOLOGY, 5th EDITION CHAPTER 1: CELLS: THE FUNDAMENTAL UNITS OF LIFE Unity and Diversity of Cells 1-1 Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be desc...

Know the lower limit of resolution for the light microscope Correct Answer-0.2 um Total magnification vs magnification of the oil immersion lens Correct Answer-Total magnification: product of the magnification of the ocular (10x) and the objective lens Oil immersion lens Define Resolving power Correct Answer-the ability of a microscope to differentiate two closelyk spaced objects as being distinct from one another Know how resolving power relates to magnification Correct Answer-Resolvi...

Who is the father of microscopy? Antonie van Leeuwenhoek Lamp: produces visible light to illuminate the specimen Condenser: collects light and directs it through the stage opening (converges or focuses the rays of light to a single point) Iris diaphragm: regulates the amount of light available to the objective lens Factors that affect microscope function: Resolving power, numerical aperture, magnification, working distance Resolving power: ability of a microscope to differentiate two ...
