Cell Analogies Project
Transcript of Cell Analogies Project
so it separates the animal cell from all the other cells.
It also allows molecules to pass through. Cell Membrane Analogy: A Gate why?: Because the cell membrane regulates what enters and exits the cell like a gate. It also protects and supports whatever is inside. The Nucleus, the "control center" for all activity, contains the hereditary of the cell. Function: Nucleus Analogy: The City Hall I will be doing the analogy of the Animal Cell. Rather than just comparing the parts to random objects, all of the cell parts will make up a city. Just like how the parts make up the animal cell in general, hey I already made an analogy! why?: The nucleus is like the city hall of a city because it is the area with all of the main information. It controls most of the city by sending out information that it needs to function. Function: The ribosomes synthesize proteins for the cell. Ribosomes Ribosomes Analogy: Lumber Yard Why?: The ribosomes are like a lumber yard because they perform protein synthesis for the nucleus. Bringing together raw ingredients such as RNA and amino acids to make proteins. The proteins are like machinery for cell functions. Such as plumbing and electricity which is needed in a city. Function: The smooth ER packages the secretory proteins as well as the synthesis of lipids. They also takes care of compounds that might otherwise be toxic or harmful to the cell. Smooth ER Analogy: The Manufacturing Plant why?: The smooth ER is like a manufacturing plant because
it makes proteins and fats. They are then "packaged" and sent off throughout and outside the cell using the rough ER (next). Function: The rough ER is a series of collapsed, interconnected sac like structures with ribosomes embedded on its surface. Transports the proteins made by the Ribosomes to the Golgi apparatus. Rough ER Analogy: The Roads The rough ER is like a highway, freeway, or any kind of road in the city. Just how cars travel around using the roads, ribosomes travel by the rough ER. Goods are shipped via road system. why?: Function: The Golgi Apparatus processes and packages proteins for delivery. It is sent to other organelles after they have been synthesized in the cell. Golgi Apparatus Analogy: Post Office why?: The golgi apparatus is like the post office because the golgi bodies are sorted where they need to go here. Then are packaged and distributed around the cell just like a post office would with mail. Function: The main purpose of Lysosome's is to digest. Another function of Lysosome's is the digestion of proteins, lipids, and carbohydrates into molecules that can be used by the rest of the cell. Lysosomes Analogy: Garbage/Waste Disposal The lysosome's in an animal cell are like waste disposal because they break down waste materials in the cell and dispose of them by digesting it inside of their membrane (by using different enzymes). So the garbage disposal would be just like the lysosome in a cell, it breaks up the food with blades, and disposes of them into waste pipes. Function: The mitochondria of a cell is where ATP is created through the breakdown of glucose in the cellular respiration process. Mitochondria: The Power Plant why?: The mitochondria is like a power plant because it provides power to the different cell parts and systems, making cell possible. Much like how a power plant powers the city. In the animal cell, the ATP (energy) is created through the breakdown of glucose (fuel) in cellular respiration. In the power plant, the electricity (energy) is made from coal (fuel) in combustion. Nuclear
Membrane Function: Nuclear Membrane Analogy: City Wall/Border The cell membrane is like the city border because cell membranes surround the cell and have the ability to control entrance and exit of substances. The cell membrane also protects the inner cell from any threats outside of the cell, like a city border or wall. why?: The nuclear membrane acts as a physical barrier and border. It separates the contents of the nucleus from the cytoplasm. Cytoskeleton Function: The cytoskeleton provides shape and gives mechanical support to the cell. Cytoskeleton Analogy: Steel Girders why?: The cytoskeleton is there to provide shape and support the cell. It is like steel girders/beams because the cytoskeleton is the the internal framework that gives each cell its distinctive shape. The structural steel beams and support for a building or bridge and cytoskeleton both give what they're supporting a high level of organization. Function: Chromosomes contain the DNA and genes. The genes store code for RNA and various proteins. Chromosomes Analogy: A Household/Family why?: Chromosomes in a cell is like a blood related family because just as the chromosomes contain and pass on the DNA & genes, the DNA & genes is passed from parent to offspring in the family. Nucleolus Function: The nucleolus is like the mayor because it controls and is in charge of the cell. It directs all of the cell's activities including reproduction, like when a new city is developed. why?: The Nucleolus is where the ribosomes are manufactured. Chromosomes Cytoplasm Function: Semi-fluid substance that fills the interior of the cell. The cytoplasm protects and cushions the organelles, and forms the ground substance of the cell. The main function of the cytoplasm is to hold the cell organelles of the cell. Nucleolus Analogy: The Mayor Cytoplasm Analogy: Air/Atomosphere The cytoplasm is like air because they both surround everything in the world and in the cell. The city needs air to survive like the animal cells need a cytoplasm. Also, people communicate with each other through the air just like how the organelles communicate with each other through the cytoplasm. why?: Vacuole Function: Vacuoles are used as storage for food, water, salt, protein, and carbohydrates. They also store worn-out cell parts that are already degraded and removes unwanted substances that may threaten the animal cell. Vacuoles in animal cells are much smaller than in plant cells Vacuoles Analogy: Warehouse Vacuoles are like warehouses because they store lots of different items. They can hold many substances from simple water to organic molecules. why?: Sources http://www.biologyjunction.com/cell_functions.htm http://quizlet.com/2636611/functions-of-the-parts-of-the-animal-cell-flash-cards/ http://jgimp.tripod.com/cells.html http://www.enotes.com/homework-help/what-function-vacuole-an-animal-cell-185719 http://www.biology4kids.com/files/cell_lysosome.html http://www.buzzle.com/articles/rough-endoplasmic-reticulum-function.html http://biology.about.com/od/cellanatomy/ss/endoplasmic-reticulum.htm http://www.enchantedlearning.com/subjects/animals/cell/ http://www.wisc-online.com/Objects/ViewObject.aspx?ID=AP11403 http://biology.unm.edu/ccouncil/Biology_124/Summaries/Cell.html http://learn.genetics.utah.edu/content/begin/cells/insideacell/ (look at how cool this is) http://www.tutorvista.com/biology/function-of-animal-cell
