United States Country compared to the structure of a cell
Transcript of United States Country compared to the structure of a cell
1. All living things are composed of cells
2. Cells are the basic unit of structure and function in living things
3.New cells are produced from existing cells
Organelles in an Animal Cell
9. Golgi apparatus: Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum.
10. Centrioles: One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope. Centrioles organize microtubules during cell division.
Organelles in an Animal Cell
1. Nucleus: The center of the atom which contains the protons and neutrons
2. Cytoplasm: The material inside the cell membrane, not including the nucleus
3. Cytoskeleton: Network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement
4. Endoplasmic Reticulum: Internal membrane system in which lipid components are assembled/ modified.
Organelles in an Animal Cell
5. Mitochondria: Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
6. Ribosomes: Small particles in the cell on which proteins are assembled.
7. Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell.
8. Cell Membrane: The cell membrane regulates what enters and leaves the cells. It is made up of proteins, carbohydrates, and phospholipids.
Analogy: The president and the nucleus
The nucleus is like the command center. It is in charge of everything. The president is supposed to be in charge of the United States.
Analogy: U.S. government and the cytoskeleton
In a cell, the cytoskeleton helps to maintain shape of the cell. In the United States, the government helps to maintain the shape of the country.
Analogy: The golgi apparatus and the United States postal office.
The golgi apparatus sorts, modifies, and packages proteins and other materials inside the cell. The postal office packages mail and has it sent off.
Analogy: Ribosomes and employees
In a cell, the ribosomes are like workers. They take orders from the nucleus, who is like the boss. Employees take orders from their boss, like the ribosomes do.
Analogy: Endoplasmic reticulum and a factory
The endoplasmic reticulum manufactures proteins and exports them from the cell. It also synthesizes and secretes proteins. It's like a factory. They manufacture products and have them exported elsewhere.
Analogy: Mitochondria and money
In a cell, the mitochondria is like the powerhouse, or generator. It changes energy stored in food into useful energy for the cell. It's sort of like money. Money is like a generator for our country. It's very useful.
Analogy: Lysosome and a state governor
In a cell, the lysosome breaks down lipids, carbohydrates, and proteins into small molecules which the cell can use. The lysosome makes things more manageable. In the United States, it can be hard for one person to direct the entire population. Thats why it's broken down into states, and each state has their own governor, making things more manageable.
Analogy: Cell Membrane and the United States border patrol
The Cell Membrane regulates what enters and leaves leaves the cells. It aids in protection and support of the cell. The United States border patrol makes sure people don't just enter the U.S. without a passport. It's selectively permeable, just like a cell membrane. Neither of these two let anything in.
The cell membrane regulates what enters and leaves the cells. It aids in protection and support of the cell. The cell membrane is made up of proteins, carbohydrates and phospholipids.
Phospholipids: The phospholipids are the lipid bi-layer in a cell. It is a tough, flexible barrier between cell and its surroundings. One end of the phospholipid "loves water", and the other "hates water". The end that "loves water is hydrophilic, the end that "hates water", is hydrophobic. Osmosis is the diffusion of water to a semi permeable membrane from a lower concentration to a higher concentration. Diffusion is the movement of a substance from higher concentration to lower concentration, due to molecules constantly colliding with each other.
Osmosis is the diffusion of water from a high concentration to a low concentration through a selectively permeable membrane. This means that some substances can pass through the membrane, while others cannot.
Diffusion is when molecules move from areas of higher concentrations to lower concentrations. This occurs because molecules constantly move and collide with each other. Diffusion is basically like the particles evenly distrubuting throughout the water.

Analogy: Vacuole and Storage
In a cell, the vacuole stores foods and other nutrients that the cell needs in order to survive. They can be found in either a plant or animal cell, but more so in plant cells. It is also used to store waste products before they are sent off. They're like a storage unit, where people leave their things for a temporary amount of time.
Analogy: Vesicle and Fedex
The vesicle stores, transports, or digests celluar products and waste. It can be visualized as a bubble of liquid within another liquid made up of many molecule. Basically, it's like the transporter in the cell. In the U.S., FedEx is a delivery service. In the cell, the vesicle is like the delivery service, while the same applies to FedEx in the U.S.
