Transcript of Cell Analogy Project

By: Dhuvarakesh Karthikeyan WELCOME TO CELL-CITY! The nucleus is like the city hall for a city, it controls the other facets of life in the city. In a cell, the nucleus controls the functions of the cell. Similarly, in a city, the city hall controls of the functions and regulations of the city. The nucleolus, which lies within the nucleus, produces ribosomes. Comparing it to the city, we get that city officials hire people for city building projects. Like a city hall's secretary -
mayor system, the nuclear envelope allows certain particles in and keeps the rest of the cytoplasm out. Pictures! Nucleus :: City Hall The pictures show the organelle and its analogous counterpart. Ribosome :: Worker The ribosome is a particle of RNA that is produced
in the nucleolus. It's function is to produce protein
when it combines with the Rough Endoplasmic
Reticulum. It's city-counterpart is a city laborer. The
city laborers are people involved with maintaining
community and who progress building projects.
Without the Ribosomes, Cell-City would not be able to
carry out certain functions, nor repair/maintain itself.
These people/organelles are vital in the longevity of Cell-City and are essential in making sure that Cell-City runs smoothly. Endoplasmic Reticulum (Rough) :: Work Site The Rough E.R. is used for protein synthesis in co ordinance with the ribosomes. In a city, this can be thought of as the building site for the workers of the city. Without proteins, ezyme catalyzed reactions couldn't occur, processes couldn't be executed, nor could information be transferred efficiently. The ribosomes pass through the E.R. upon exiting the nuclear pores and travel thorough the E.R. out into the cytoplasm. Golgi Body :: Mail Service The Golgi Body of cell city is its mail service, G.lobularly O.perating L.inkage G.roup I.ncorporated; GOLGI. The Golgi Body modifies molecules and substances, and sends them to their destination via vesicles - small bubble-like structures. Analogously, the mail service packages shipments, letters of info., and other such items and ships them to their destinations. Endoplasmic Reticulum
(Smooth) :: Toxic Waste Facility The smooth E.R. serves as the toxin disposal unit of cell city. It can also be referred to as the toxic waste facility. In a cell, the smooth E.R. breaks down alcohol and other toxins. In comparison, the city's toxic waste facility disposes of and neutralizes the threat of toxins spreading and damaging Cell-City. Mitochondria :: Power Plant The mitochondria are like the power plants of the cell. Here, ATP Synthesis occurs for the cell to use as energy by breaking the strong chemical bonds. Mitochondria are distinct from the other organelles in that they contain DNA similar to the bacterial genome! Similarly, a power plant provides energy for the city and is fairly independent from City-Hall. Without mitochondria, Cell-City would be powerless. City Hall Lysosome :: Waste Management The lysosome of the cell is like the waste management of the cell. It breaks down dead organelles, proteins, lipids, and during apoptosis, even the cell itself. The waste management facility breaks down waste, and recycles materials for later Cell city usage. Contractile Vacuole :: Dam The contractile vacuole of an animal cell, maintains the levels of water within that cell. If there is too much water, the cell will contract the vacuoles, pumping out the water. This is similar to the dam controlling the amount of water in Cell-City. Cytoskeleton :: Roadwork System The cytoskeleton consists of microfilaments and microtubues that provide support and transport of the cell. Made up of the protein actin and Alpha and Beta tubules, they also assist in cell division. Cell-City's road systems support and promote transportation in cell city as well. Cell Membrane :: Immigration office The cell membrane of the cell is a semi-permeable membrane that allows certain particles through and halts certain particles outside the membrane. Like the cell membrane, the immigration office of Cell City controls which people can stay within the city and which particles must leave or cannot get in. Flagella + Cilia :: Truck Fleet The flagella and cilia are what allow the cell to move throughout a substance. They can be compared to a truck fleet as in Cell-City the truck do the transporting of really heavy objects, and can relocate the city antecedent to a terrible disaster. Flagella Thanks for Watching!!!

Now go ace your test! Just Win Baby!
