Cell compared to a city
Transcript of Cell compared to a city
The city of Bru"cells"
The function of the nucleus in a cell is to act as the cell's control center by using nucleic acids to direct all of the cell's activities. The town hall represents the cell nucleus because it controls the city and the activities of the different city parts, much like how the nucleus operates the different cell parts.
The function of the cell wall is to support the cell and protect it from things outside of it. The big fat city wall represents the cell wall because it protects the city from things outside of it, much like how the cell wall does this for the cell.
Grass (open space)
The function of the cytoplasm within the cell is to contain all the different organelles. The grass (or open space) of the city represents the cytoplasm because it contains all of the different city parts within, much like how the cytoplasm contains all of the organelles within itself.
The function of the Golgi apparatus in the cell is to use Golgi bodies to ship the products of the endoplasmic reticulum to where they are needed inside and outside the cell. The post office represents the Golgi apparatus because it also delivers things to where they are needed in the city, much like how the Golgi does this for the cell. Also, the post office delivery trucks represent the Golgi bodies, as they both go off from where they belong to transport needed materials to where they need to go.
The function of the endoplasmic reticulum in the cell is to produce and store important materials needed by the cell, such as lipids, carbohydrates, and proteins. The factory of the city represents the endoplasmic reticulum because it manufactures things that are needed by the city, much as the ER does for the cell.
The function of the ribosomes in the cell is to attach to the endoplasmic reticulum and produce the materials that are needed by the cell; proteins, lipids, and carbohydrates. The laborers of the city represent the ribosomes because they go to the factory (endoplasmic reticulum), and manufacture and store things that are needed by the city, much as the ribosomes produce things needed by the cell.
The function of the mitochondria in the cell is to generate energy for the cell from glucose and oxygen. The power plant of the city represents the mitochondria because it generates power for the city, just like the mitochondria does for the cell.
The function of the vacuole in the cell is to store extra food and water (among other things) for the cell. The water tower of the city represents the vacuole because it stores a large amount of water for the city, just like how the vacuole stores water for the cell.
The function of the lysosomes in the cell is to break down large food particles into smaller ones, and to recycle old cell parts into usable materials. The recycling center of the city represents the lysosomes because it recycles old and worn out things into usable materials for the city, much as the lysosomes do with the old cell parts.
The function of the chloroplasts in the cell is to capture solar energy and convert it into a form the cell can use in the process of releasing energy (glucose). The solar plant of the city is like a chloroplast because it uses solar panels to capture solar energy and convert it into a form that is usable by the city (electricity), just like the chloroplasts do for the cell.
The function of the cell membrane in the is to control what materials move in and out of the cell, and to provide structure for the cell. The toll booth of the city represents the cell membrane because it regulates what moves in and out of the city, much like the cell membrane does for the cell.
