Document Summary
Cell biology- a discipline that studies cells (the basic structural, functional and biological unit of all known organisms. Cell biologists look at all aspects of the cell in terms of: cell structure, cell organelles and membrane trafficking, cell cycle, division, and death, cell movement, cell signalling, cell communication. It is a part of core in biology. Determine what is normal so we can fix the abnormal . Ultimate goal: to understand how macromolecular systems and organelles work and cooperate to enable cells to function autonomously and in tissues. Organelles are materials contained in a plasma membrane, different cells have different components but they share the same fundamental organelles. Once the tools are complete, we can start answering questions pertaining to out ~75 trillion cells and. In vitro: inside glass dish, but nowadays it refers to simply plastic dishes due to cost. Cell culture- technique used to grow cells or tissues outside the original organism under strictly controlled conditions.
