The Cell - A Microcosm of Life

             It is the miniature version of the world, an epitome of the universe. It can be compared to a community that is composed of different people doing their respective jobs and functioning together to fully sustain their everyday life. It is equal to a country that has its leader, subordinates, different departments and industries that support the government and its people per se.
             A cell has its plasma membrane that surrounds and encapsulates it. The plasma membrane is the Department of National Defense (DND) of the cell. These membranes are soldiers responsible for guarding against external threats to peace and security of the cell. The hydrophobic core of the bilayer is the defense that protects the cell from its potential enemy by inhibiting water-soluble compounds (enemy) from passing in and out of the cell. On the other hand, the integral transport protein can be the ambassador that allows essential water-soluble substances to cross the plasma membrane. Additionally, the hydrophobic bilayer helps retain essential water-soluble substances within the cell as how the DND protects ally countries visiting the country. The endoplasmic reticulum is the Department of Transportation and Communications (DOTC) since it is a network of membranous channels pervading the cytoplasm and providing continuity between the nuclear envelope, the Golgi apparatus and the plasma membrane. The cytoplasm cater communications by connecting various membranes of the cell. .
             Through this interconnection, it becomes possible for a signal to be generated at one part of the cell to be transmitted quickly and efficiently to other regions of the cell. The Golgi apparatus is the Department of Education where membrane differentiation and the development of surface specificity occurs as how students decides what career to pursue while in school and what specific profession to choose. The mitochondrion, the powerhouse of the cell, is the Department of Energy which is responsible for most of the metabolic energy (adenosine triphosphate) produced in the cells.
