Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the second of four Science Objects in the Cell Structure and Function SciPack. It explores the various organelles within a cell and each organelle’s function. Every cell is surrounded by a membrane that separates it from the outside world. This membrane controls what can enter and leave the cell. Inside cells exists a variety of specialized molecular structures (organelles) that carry out such functions as energy production, transport of molecules, waste disposal, synthesis of new molecules, and the storage of genetic material. All these molecular structures function as a coordinated system that works in a delicate balance of chemical and physical reactions. In addition, most cells of multi-cellular organisms perform some special functions that other cells do not.
