Why Is an Animal Cell Like a Hospital Analogy

Illustration - Cell

The prison cell is the basic unit of measurement of living systems. Although information technology is relatively like shooting fish in a barrel to visualize the components of cells, it is difficult to conceptualize how these components function together to sustain life within the prison cell. To develop an agreement of the functional processes that take place in a prison cell, information technology is helpful to draw an illustration to an automobile manufacturing plant.

Target concept

: The lexicon defines a prison cell as "the smallest independently operation unit in the construction of an organism, usually consisting of ane or more nuclei surrounded past cytoplasm and enclosed in a membrane". Although this is a relatively accurate clarification, it is non an intuitive description that students tin readily relate to. Considering cells are microscopic, difficult to visualize in three dimensions, and exceedingly circuitous in function, about teachers depict analogies to help students grasp their significance. It is common to hear teachers depict analogies between cells and cities, schools, and factories. In this example we are illustrating an analogy between a cell and a manufacturing plant, but it should be understood that others can exist equally well developed.

Analogue concept

: An analogy is helpful only when people are familiar with the analogue concept, in this instance a factory. Relatively few students take visited factories, and so it is helpful to review the system of a mill every bit the analogy is developed. A factory is a facility where goods are manufactured for export. A factory consumes raw materials and energy in an endeavor to sustain its workers and provide resources to others. This is analogous to the operation of a cell (figure ten.five) as seen in the following mapping.

Relevant features / Mapping:

cell « factory: A prison cell (in a multicellular organism) is an identifiable unit of measurement that is part of a larger organism but as a manufactory is an identifiable unit of measurement that is role of guild. A cell uses textile and energy resources and produces products merely as a manufacturing plant does.

cell products « manufactory products: Cells practise non work in isolation just provide and receive resources from other cells or from the surrounding surroundings. Factories produce products so that they may be sold and earn coin for the corporation. Similarly, cells produce products that may exist used past surrounding cells, and in turn receive resources from surrounding cells. For example, cells in the Beta Islets of Langerhans in the pancreas produce insulin that is used by surrounding cells. Simultaneously, these same cells receive oxygen and nutrients provided by the ruby blood cells and plasma that catamenia in their neighborhood.

organelle membranes « walls: In factories, walls are used to separate regions with different functions. For example, the paint room is separated from the upholstery shop and then each can carry on its functions without interference from the other.

nucleus « headquarters: The nucleus of a cell controls the operations of a cell. In a like way, manufactory headquarters controls the operations of a factory. The nucleus is separated from the residue of the cell by a nuclear membrane that allows it to office without intermission from surrounding organelles, simply as the office walls of the headquarters allow planners and managers to direct the operations of the manufactory without being distracted by surrounding operations.

nuclear pore « doors: Advice is essential to the proper functioning of a factory. Doors allow people from unlike departments to visit and communicate. In a similar manner, nuclear pores allow for information and resources to period between the nucleus and the cell it manages.

DNA/chromosome « plans: Each factory has plans that govern the production and evolution of their products, as well as plans that govern the day-to-day performance of the factory. DNA is analogous to such plans, providing the code not only for all cell products, but likewise the proteins that govern daily operations within the cell.

shine endoplasmic reticulum « hallways: Factories accept hallways through which information from the office travels to the workers in all departments. Similarly, the cell has smooth endoplasmic reticulum through which it is believed that messenger RNA travels from the nucleus to places where it is decoded.

ribosome « worker: Manufactory workers "translate" instructions from headquarters into products. In an analogous way, ribosomes are the site where messenger RNA is translated into proteins.

rough endoplasmic reticulum « associates line: Workers gather in regions of the manufacturing plant where assembly takes place. Similarly, ribosomes are positioned on rough endoplasmic reticulum where the proteins are assembled.

protein « product: Factories produce products for internal and external use. Similarly, cells produce proteins for internal utilize and for export. Proteins result when Dna code has been transcribed into RNA and translated into polypeptide chains. Similarly, manufactory products result when plans from the part are copied and distributed to workers who combine various components to gather a production.

cytoplasm « stock room: A manufacturing plant needs a stock room from which parts can be taken for use on the associates line. Similarly, resource are distributed through the cytoplasm until they are used past surrounding organelles.

one thousand-RNA « photocopy: Although the master plans of a company may be protected in the manufactory headquarters, individual plans may be photocopied from these plans and distributed to workers every bit needed. one thousand-RNA is like a photocopy of Dna that accurately transmits information from the nucleus to the ribosomes where it is translated into useful proteins.

t-RNA « stockroom helpers: Stockroom helpers bring components to the assembly line where they tin be combined into products. Similarly, t-RNA brings amino acids from the cytoplasm to the ribosomes where aggregation of proteins may accept place.

mitochondrion « powerhouse: A powerhouse converts energy from one form to another. For instance, the powerhouse at a hydroelectric dam converts the kinetic energy of falling water into electrical energy for distribution to homes and businesses. In a similar mode, mitochondria convert free energy from the bonds in glucose to the phosphate bonds of ATP.

ATP « electricity: Electricity is a flexible energy source that tin can be easily distributed to homes and businesses. Similarly, ATP is a flexible free energy source that is used to power the growth, motion and metabolism of the cell.

Golgi apparatus « warehouse: Products from a factory are by and large stored in a warehouse before exporting. The Golgi apparatus may serve as a warehouse where proteins are stored prior to export.

Limitations: This analogy should not be extended to prison cell partitioning. Whereas industries grow by the addition of new factories, cells grow past the splitting and growth of existing cells. Thus, students should not effort to observe analogues for such things every bit asters, centrioles, spindle fibers, etc.

Student activity: Working in a squad, develop a new analogy for a cell. You may wish to analogize a cell to a city, your school, your domicile, or some other entity of your choice.
