Transcript of Cell City Presentation

Cell Cities A City Within a Cell The nucleus controls what the cell is doing and
it contains genetic information about the cell, so it controls its characteristics. Nucleus The simplest part of life
(can carry out life's functions). Cell with an example of my city created here. Now Let's get Started This is a simple
visual of the nucleus in
a plant cell Pretty basic huh? A city hall in a city is the
center of government. It has control over the laws and make sure everyone is doing the right thing, so it's in charge of the city. City Hall As you can see, cells are very
small, hence the definition
earlier, but don't they have a lot of things in common with cities? This is an Example of a cell New Life City The post office, in the civilized world,
is very important to get objects where they need to be. Postal service delivers, sorts, and ships stuff around the world. Post Office Golgi Complex The golgi complex is responsible for transporting macromolecules to somewhere else. Similar to the post office, it packages the material and then deliver it to another place. Garbage Dump A garbage dump or
landfill controls and
breaks down human
wastes. It collects garbage
from waste services
and they slowly decompose. Lysosomes Lysosomes, in organisms,
break down waste and cell debris (bacteria). Therefore, they control the
level of wastes, toxins, or unwanted
stuff inside our cells. A city needs its way
to get rid of waste, too so they throw it into
the dumpster. Power Plants Power Plants
are essential for
providing the energy
and resources to keep
cities running alive and well As subtle as the subject may be, building foundations are the key to keeping our city together and whole in one place, and it prevents stuff from falling over. Foundations let us build important buildings that perform certain tasks. Building Foundations Mitochondria Without mitochondria, our cells
won't have the energy to move, divide, and perform other celluar functions.
Like power plants mitochondria harnesses energy (sugar) to keep the cell alive and useful. Farm Farms provide food and agriculture for our city to run and thrive as needed. With no farms, cities cannot grow and will probably starve. Farms, like chloroplasts, also give some color to the landscape. Chloroplasts Chloroplasts, although only found in plant cells DO play an important part in plant life. Chloroplasts produce a sugar food called glucose through photosynthesis. This glucose then gets consumed by the plant, giving it energy and the ability to grow
Chlorophyll, found in chloroplasts give the plant its green color in order to get energy from the sun. Not all cities have dams, but this one does for the sake of purpose. Anyway, a dam provides energy for the city using hydroelectric power.
Cells don't do that but the other purpose of a dam is for effective flood control. For cities that run through rivers that tend to flood, a dam helps keep the water level under control and prevents the city to be overrun by H2O. River Dam Although a cell membrane looks absolutely nothing like a dam, it serves the same purpose. For cells... The main job of the cell membrane is to control the flow of liquids into and out of the cell. Some parts of the membrane are hydrophobic, and some are hydrophilic. Plus it contains proteins that allow our senses to function. Cell Membrane The cytoplasm is mostly gel like liquid that holds other organelles in place like a foundation. It also controls cell metabolism to maintain the living cell. Cytoplasm Markets are very essential to the economy and the growth of the city. The food provide nutrients for our people. Markets Commonly found in plants, a vacuole is like a market because it can store nutrients and it helps the growth of cell. One function of only the vacuole is that it control the turgor pressure inside the cell. Central Vacuole The hospital mend our people and cure diseases.
The most important part of the hospital for this project is that patients can go there to give birth to new people, and this reason will be explained on the next slide. Hospital A Nucleolus produces ribosomes which represent people in this presentation, which is important to protein synthesis. Nucleolus People are like ribosomes themselves
and the protein they produce. People also build cities like proteins build cells and work in numerous groups like ribosomes. People! Ribosomes are important in protein synthesis.
They're like people because many of them work.
to help produce proteins. Proteins build cell structure, so its like workers building a city. People control how the city runs and that is what the protein from ribosomes do, they control cell processes. Ribosomes A work office contains people working in it to perform a task. Like an endoplasmic reticulum
the work stays in the office waiting to be distributed. Work office The endoplasmic reticulum collects proteins made by ribosomes for transport and the ribosomes themselves. Smooth endoplasmic reticulum are important for lipid steroid synthesis. Endoplasmic reticulum The city limit is the boundary where the city's influence ends. It also gives some shape and structure of the city because you can visualize the boundary. City Limit The cell wall is only in plant cells. It provides, shape, support, and the structure for the plant as well as protection. Cell wall Welcome Thanks for watching this presentation! :) by: Roger Zhong
