Essay / Research Paper Abstract

This 5 page paper outlines the view that the study of cellular function and the variety of different techniques used in cell biology relate to the complexity of cellular structures. Theorists like Warren Weaver, for example, recognized the concept of “organized complexity” and related this in terms of efforts to provide a rational account of biological organization. Bibliography lists 6 sources.

example, recognized the concept of "organized complexity" and related this in terms of efforts to provide a rational account of biological organization (Harold, 2001, 4). "We have ample reason to believe that every biological phenomenon, however complex, is ultimately based on chemical and physical interactions among molecules. With this principle as a point of departure, intense efforts are presently underway to understand how and when a flower identifying all the relevant molecules and describing how they intermesh" (Harold, 2001, 4). Harolds (2001) central hypothesis, then, is that the way we understand the basic elements of life, cellular biology and even the pursuit of RNA and DNA sequencing, is cumulative, it is built on layers of information that are constantly changing and being redeveloped. As a result, even efforts that appear to be the most complex and well defined may be completely altered in the presence of new research. And new research is occurring all of the time. As a result, the use of specific techniques, including light microscopy, measurement of cell organelles, and the demonstration of the mitochondria has occurred through a recognition of this complexity. Light Microscopy Light microscopy is the study of cells utilizing a microscope that is dependent on illumination to create contrast. Contrast formation is defined by the ratio between light and dark, and light microscopy often integrates the use of stains in order to better determine the contrast that is created (The Light Microscopy Page, 2003). In a compound microscope, there is a light source that allows the light to pass through the specimen (a slide) and is then collected by a set of optics (The Light Microscopy Page, 2003). "Dissecting (stereo) microscopes generally use episcopic illumination for use with opaque specimen. The ...
