Transcript of Cell City Project

Cell City Nucleus The nucleus would be the city hall of cell city. It is the central part of both animal and most plant cells. The nucleus contains the cell's heredity information and controls the functions of the cell. This is similar to how the city hall keeps information relating to the city and is the place where major decisions are made to keep the city functioning efficiently. Mitochondria The mitochondria would be the power plants in cell city. Their main function in cells is to provide energy for the cell. This is done by transferring energy from organic compounds (like glucose) to ATP. The ATP molecule is used as an energy currency among cells. Energy from ATP drives most chemical reactions in that occur in a cell. Power plants are similar because they heat water with coal to produce steam which spins turbines, like a chemical reaction. This spinning of turbines produce electricity which is like ATP. Ribosomes The ribosomes would be would be the numerous factories of cell city. In cells they have the important role of synthesizing protein. Protein has many applications in the body, making it a vital. Examples include building muscle, repairing, and other bodily functions. Factories are similar to ribosomes in which they produce useful goods. Goods produced by factories can have many purposes for people of a city and other cities. Smooth & Rough ER Both the smooth and rough endoplasmic reticulum would be the various highways and roads in cell city. Rough ER prepares protein for export and is dotted with ribosomes. Smooth ER stores ions for later use and calcium for detoxifying substances. They can be similar to roads and highways in cities because vehicles are used to move things and people throughout the city. Rough ER can be seen as an exiting city highway and smooth ER as entering city highway. Golgi Apparatus The golgi apparatus would be the post office in cell city. Its main function in cells is to package molecules like fats and proteins . Proteins are sometimes processed and changed by enzymes as it passes through the golgi apparatus. These materials can either be stored in the golgi apparatus, released to be part of the cell membrane, or released to travel to other parts of the body through active transport. In a way, post offices function in a similar way. They transport goods and letters throughout the cell or receive them and export them out of the city to be delivered around the world. Chloroplast The chloroplast would be numerous trees, other plants, and farms in cell city. Chloroplasts are organelles that are used by plants to convert energy from the sun into chemical energy in organic compounds like starches and sugars. This process is called photosynthesis. Trees and other plants in a city would basically do the same thing including providing oxygen and getting rid of CO2 from the air. Farms would provide vegetables and fruits for people in the city. Plants in general would make the city look more natural, provide food, and lessen pollution. Lysosome The lysosomes would be the recycling and waste disposal center in cell city. They have an important role in cells which is to digest things like worn out organelles, bacteria, and food. Each lysosome contains digestive enzymes used to break down food and waste material. Lysosomes can either breakdown materials into compounds to be used or discarded by the cell. Essentially they ensure that anything that passes through the cell can be used with maximum efficiency or discarded when it can't be used. A recycling and waste disposal center would be similar because both either get rid of waste from the city or recycle it into something usable. Cell Membrane The cell membrane would be the city limits and ring road of cell city. The cell membrane is used to define the integrity of the cell and determines what can pass and exit the cell. A cell membrane can either be semi-permeable or not permeable at all. Things can either be transported through diffusion, facilitated transport, or active transport. City limits would define the definite border of a city to be used for demographic purposes. A ring road would surround the city. There would be security gate that would either allow people to enter or not enter the city. Cell Wall The cell wall would be cell city's defensive wall. In plant cells, the cell wall functions as structural support for a plant and extra protection for plant cells. Also, other functions include filtering and prevention of rupture from water osmosis. It is made up of mostly cellulose. A defensive wall can be used in an event of wars or floods. They can also be used to form a border between cities. Vacuole The vacuole would be the water tower of cell city. In plant cells, the vacuole is close to the center of the cell. It is filled up with water and other molecules. It helps maintain structural support for the plant by tugor pressure. The vacuole also functions as a waste storage and nutrients storage. A water tower would be similar to a vacuole because it contains water which would be needed by the city and it also provides high pressure needed to make water travel efficiently. Cytoskeleton The cytoskeleton would be the foundation and support beams of the buildings in cell city. In eukaryote cells, the cytoskeleton provides support, shape, elasticity, and protection for the contents of the cell. It also provides a cellular scaffold to keep the nucleus in place and help organelles move around. A city would need foundations beams for buildings because without them the ground would break down under them and buildings would be unstable and collapse. Therefore, it is important that every building has stable and strong foundations and support beams.
