Document Summary
Cell biology is an academic discipline that studies, the basic structural, functional and biological unit of all known organisms. Anything that tis alive is composed of cells. Cell biologists looks at all aspects of the cell. Part of the core in biology we only know a small fraction about cell. Determine what is normal so we can fix the abnormal medicla implication. Storehouse for thousands of genes there is symbiotic relation between genes and cell. Electron micrograph primary focus on eukaryotic cells i. e. once w/ nucleus. Ultimate goal: to understand how macromolecular systems and organelles work and cooperate to enable cells to function autonomously (alone) and in tissue (w/ other cells) Once you have the tools, we can start to ask, and more importantly begin to answer, biological questions pertaining to our ~ 75 trillion cells. In vitro: outside the body in an artificial state. Technique used to grow cells or tissues outside the organism under strictly controlled conditions.
