-The nucleus is to a cell as city hall is to a city.
-Just as the nucleus of a cell contains the information and controls the activity of the cell, City hall contains all the information of a city and controls how the city is regulated.
-The nucleus is made up of chromatin, nucleolus, and a nuclear envelope, and it contains the genetic information of the cell, and controls its activity.
-The nuclear envelope is to a cell, as city hall’s lockable doors are to a city.
-Just as the nuclear envelope acts as a selectively permeable outer layer for the nucleus in a cell, the lockable doors of city hall are used to decide who or what can be brought in and out of city hall

-Chromatin is to the cell, as the blueprints of a city are to a city.
-Just as chromatin contains information on the construction of the cell, Blueprints of a city contain information on how the city was made.
The Term Paper on Stem Cell
Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic, adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral, ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must ...
-Chromatin is made up of DNA and proteins, and it contains information on how to make the cell.
-Ribosomes are to the cell as a brickyard is to the city.
-Just as Ribosomes make up proteins which are essential for the building and activity in a cell, the brickyard makes bricks which are essential in the building of a city.
-Ribosomes are round structures with multiple copies of rRNA that manufacture proteins
-Rough and smooth Endoplasmic reticulum is to a cell as roads and highways are to a city.
-Just as rough and smooth ER are places where products in the cell can be transported, roads and highways are places where goods can be transported in a city
-Rough ER manufactures and membranes and secretory products and is made up of a network of membranes with attached ribosomes, but the smooth ER is made up of a membrane network without attached ribosomes, and it synthesizes lipids, detoxifies drugs and stores and releases ions.
-The golgi bodies are to a cell as a post office is to a city.
-Just as the golgi bodies ship goods created by the ER to the rest of the cell, The post office ships goods throughout the city to certain people.
-The golgi bodies are stacks of flattened sacs, or cisternae, which are not physically connected, and they synthesize and send products of the ER to the other parts of the cell.
-Mitochondria are to the cell as a power plant is to a city.
-Just as the Mitochondria provide ATP for the cell to use as energy, the Power Plant of the city provides electricity for the city to use as energy.
The mitochondrion is a double membrane structure. The inner membrane (cristae) is where aerobic respiration takes place, and it generates ATP.
-Chloroplasts are to the cell, as a solar energy plant is to a city.
-Just as Chloroplasts use the sun’s energy to create energy in a cell, The solar energy plants use sunlight to create energy for the city.
-Chloroplasts are made up of a double membrane sac containing stacks of membrane sacs, and it is the site of photosynthesis.
-Granum is to the cell as the towers of a solar energy plant are to a city.
The Essay on Body Cells Carbohydrates Energy
Carbohydrates supply us with the energy needed in our daily activity. Carbohydrates are essay to convert to glucose, the fuel for body cell. Lacking glucose will direct affect to our moon and behavior. Simple sugar and complex carbohydrates are the two major forms of carbohydrates. Proteins are repairing bone, muscle, skin, and blood cells. Proteins are also protecting us from disease, such as ...
-Just as granum stack up to form part of the chloroplast, towers are made to form part of the solar energy plant.
-Stroma is to a cell, as solar panels in solar energy plants are to a city.
-Just as Stroma surrounds the granum to form chloroplasts, Solar panels surround towers to form solar energy plants.
-Together, Stroma and granum form chloroplasts in order to cause photosynthesis. Granum are made up of stacks of thykaloids and the stroma is a fluid that surrounds it.
-A cell wall is to the cell, as a city wall is to a city.
-Just as a cell wall protects the cell by surrounding it, a city wall protects the city it surrounds.
-A cell wall is made up of cellulose, other polysaccharides, and protein.
-Central Vacuole is to the cell as garbage dump is to city.
-Just as the central vacuole stores and breaks down waste in the cell, a garbage dump stores breaks down the waste in a city.
-The central vacuole stores and beaks down waste inside the plant, and it is made up of tonoplasts and cell sap.
-Lysosome is to a cell as a trash man is to a city.
-Just as lysosome goes through the cell digesting and breaking down unwanted macromolecules, a trash man goes throughout the city getting rid of unwanted trash.
-Lysosome is a sac with hydrolytic enzymes and an acid pH that digests macromolecules.
-Peroxisome is to a cell as a garbage man’s assistant is to a city.
-Just as peroxisome can is limited to its capabilities in what it can break down, a trash man’s assistant is limited to getting rid of all waste due to lack of experience.
-Peroxisome is roughly spherical with a granular or crystalline core, and it breaks down certain macromolecules and produces hydrogen peroxide.
-Cytoskeleton is to the cell as police enforcement is to a city.
-Just as the cytoskeleton keeps the cell’s shape in a cell, the police enforcement helps the city stay in safe from crime and in shape.
The Term Paper on The Different Types of Cells
There are three major parts of a cell-- the nucleus, cytoplasm, and cell membrane, if these are stained appropriately, they can be easily seen under a light microscope. The nucleus (in many cell types) is the innermost and is enclosed by a thin membrane. The nucleus contains the genetic material which directs the cells function. The cytoplasm includes specialized structures called cytoplasmic ...
-Cytoskeleton is made up of microfilaments, intermediate filaments, and microtubules, and it reinforces cell’s shape and function’s in cell movement.
-Flagella and cilia are to a cell as, trucks are to a city.
-Just as cilia and flagella are involved in the locomotion of a cell, a truck is used to move things in a city.
-Flagella and cilia are both made up of microtubules.
-Dynein arms are to a cell, as the wheels of a truck are to a city.
-Just as the dyneim arms are responsible for the movement of cilia and flagella, wheels are responsible for the movement of a truck.
-Dynein arms are molecules that extend from microtubules that are responsible for the movement of flagella and cilia.
