Transcript of Cell Analogy
In a city its skeleton is made up of two basics components: the
foundation and the community. The foundation is obviously
made up cement, but the community is what gives this
skeleton movement. Inside communities there are many
revolutionary people who help the community take the right
strides to a brighter future. As well as the patriots we have the
do-gooders, the humanitarians in the community. They are the ones that are constantly reaching out, and extending a helping hand within the city and community. by: Plant Cell Analogy Emily Dannielle I n this project we will be exploring the similarities of a cell to a city. Just like a city, a plant cell has many different components that are key to its functions. & Plant Cell Organelle: Part of the city cELL mEMBRANE

FOUNDATION IN A COMMUNITY Cell Membrane: The cell membrane's main job is to keep the cytoplasm inside the cell. In addition to that, the cell membrane also allows nutrients in and waste products out. In our city analogy, we are comparing the Cell Membrane to a city wall. Just like how the cell membrane protects all the organelles within the cell, the city wall surrounds and protects the city. The Cytoplasm of a cell is the main substance that takes up all the space the other organelles do not. Like the cytoplasm, the atmosphere keeps and holds the components of the city. Cytoplasm Cytoskeleton Containing all of the genetic material, and DNA the nucleus is the brain of the cell; the nucleus controls and directs all cellular activities. The Mayor’s office in a city holds a similar power, it contains and holds all of the information about the city; information on the history and residents that reside there, and the basic makeup of the city. It also controls all other basic functions within the city, like waste disposal and transportation. Nucleus The golgi apparatus is responsible for packaging substances received from the endoplasmic reticulum and transporting them out of the cell. Truckers do a similar job; they typically transport packaged goods in and out of the city. Golgi Apparatus Lysosomes contain enzymes that digest
food, destroy bacteria, and break down
damaged organelles in cells containing nutrients. City dumps do the same thing, over time they hold wastes and other damaged goods while they break down and decompose. The natural bacteria found in dumps only makes that process that much quicker. Lysosomes The mitochondria is the place in the cell where reactions occur to convert chemical energy in sugars into energy the cell can use. Like the Mitochondria a power plant found in a city converts natural resources into energy that can power the city. Mitochondria Ribosomes Endoplasmic Reticulum In an Endoplasmic Reticulum there are two parts, Smooth ER and Rough ER. Much like a highway, the rough ER is in charge of the transportation of protein, like a truck transporting a herd of swine. The smooth ER on the other hand is in charge of transporting oils and fats, similar to an oil tanker. Two subunits in a cell that work together to build, and assemble protein are commonly known and labeled as Ribosomes. Like ribosomes, a butcher provides and assembles meat for his customers. Vacuoles and Vesicles Plants may use vacuoles to store water. Those tiny water bags help to support the plant. They work together with the organelles called vesicles that are found throughout the cell.
We decided to use a storage facility to compare to a vacuole since both store objects that are valuable to both the city and cell. References: http://answers.yahoo.com/question/index?qid=20091023221320AAgOnWS
