ANALOGY OF CELLS AND FACTORIES

PREPARED AND PRESENTED BY ARDY & ELENA

WHAT IS A CELL?A cell is the basic unit of living systems. It is the smallest independently functioning unit in the structure of an organism. ("Cell Parts W/factory Analogy Flashcards | Quizlet.")It is the smallest living thing. Even though they are small, they can form tissues that themselves form organs and eventually entire organisms. (There are many different kinds of cells; two that we will be focusing today are animal cells and plant cells. ("What Is a Cell? | Learn Science at

Scitable.") There are some similarities and differences in both types. (V, Jim. "What Is a Cell." )

CELL = FACTORY

A cell (in a multicellular organism) is an identifiable unit that is part of a larger organism just as a factory is an identifiable unit that is part of society. A cell uses material and energy resources and produces products just as a factory does. (("Cell Parts W/factory Analogy Flashcards | Quizlet.")

CELL MEMBRANE = FRONT DOORA cell membrane surrounds the cytoplasm (stock room) and it controls the entry and exit of dissolved substances. The job is equivallent to a front door in a factory. ("Untitled Document." )

BOTH IN ANIMAL AND PLANT CELLS ONLY IN PLANT CELLS

CYTOPLASM = STOCK ROOMA factory needs a stock room from which parts can be taken for use on the assembly line.  Similarly, resources are distributed through the cytoplasm until they are used by surrounding organelles. ("Cell Parts W/factory Analogy Flashcards | Quizlet.")

BOTH IN ANIMAL AND PLANT CELLS ONLY IN PLANT CELLS

NUCLEUS = MAIN OFFICEThe nucleus of a cell controls the operations of a cell.  In a similar manner, factory headquarters controls the operations of a factory.  The nucleus is separated from the rest of the cell by a nuclear membrane that allows it to function without interruption from surrounding organelles, just as the office walls of the headquarters allow planners and managers to direct the operations of the factory without being distracted by surrounding operations. ("Untitled Document." )

BOTH IN ANIMAL AND PLANT CELLS ONLY IN PLANT CELLS

CHLOROPLASTS = SOLAR PANELS

The chloroplast collects sunlight in plants; where photosynthesis takes place. Similarly, the solar panel in a factory does the same thing. A solar panel collects energy from the sun and produces it as another form of energy to run the factory. ("Untitled Document." )

BOTH IN ANIMAL AND PLANT CELLS ONLY IN PLANT CELLS

MITOCHONDRION = POWERHOUSEA powerhouse converts energy from one form to another.  For example, 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 manner, mitochondria convert energy from the bonds in glucose to the phosphate bonds of ATP. ("Untitled Document." )

BOTH IN ANIMAL AND PLANT CELLS ONLY IN PLANT CELLS

RIBOSOME = WORKERFactory workers “translate” instructions from headquarters into products. In an analogous fashion, ribosomes are the site where messenger RNA is translated into proteins. ("Untitled Document." )
