Transcript of Cell Analogy

A Journey Into An Ancient Egyptian Town
Vesicles
Nucleus
Bow down to the mighty nucleus, the godly Pharaoh! He is the "great house," and directs and controls the whole city and kingdom. Just like the nucleus contains all the information for the cell and directs it, the pharaoh contains all the information for the city and kingdom and controls its movements.
The pharaoh was believed to be a god
on earth, and held the most power;
the pharaoh made laws and kept the order
within his kingdom.
The word Pharaoh itself translates
to "Great House." Just like the nucleus
contains the information for the cell's
movements, actions, and division, the
Pharaoh holds all the power over his
dynasty and its movements and actions.
Both the nucleus and the pharaoh keep
their cells and kingdoms running.
Ribosomes
Ancient Egypt is famous for its talented artisans and craftsmen. Ribosomes are responsible for protein synthesis; artisans and craftsmen were responsible for creating art and useful commodities and items. Just like ribosomes create proteins out of animo acids, crafters and artisans used basic materials and created works of art or products out of them.
Movement of goods and items would be accomplished by merchants and traders. Merchants and traders would sell their goods, either in a close marketplace or further out through the city, or even outside of the city, trading with other people. Vesicles carry the materials from the endoplasmic reticulum and golgi apparatus to other parts of the cell, and even out of the cell. Just like the vesicles transport proteins and other molecules throughout the cell and outside of the cell, the merchants would carry finished products and food throughout the city and surrounding areas.
Rough Endoplasmic Reticulum
Here is where most artisans and craftsmen (ribosomes) go to create their art and products. The rough endoplasmic reticulum is responsible for further altering the polypeptide chains synthesized by the ribosomes. Just like the rER provides a place for the ribosomes to create their proteins and chemically changes the proteins themselves, these workshops offer a place for the craftsmen and artisans to deposit and create their work and further change it. The workshops themselves would essentially finish off some products, such as the finishing of clay pots in a fire.
Cell Membrane
Surrounding the whole town is an authentic, man-made, labor-made wall that provides protection from invading armies and rulers. There are strategically placed gates and channels that regulate the flow of people, goods, and objects. Just like the cell membrane provides structure and regulates what enters the cell, this wall and its gates control who and what enters and leaves the city.
An Animal Cell Analogy

Cell Theory
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
Diffusion is the movement of molecules
from an area of high concentration to an
area of low concentration.
Osmosis is the diffusion of, specifically, water, across a selectively-permeable membrane.
Phospholipids are lipids composed of a
hydrophilic head containing a phosphate
group and a glycerol group. They also
have hydrophobic fatty acid tails
composed of long chains of carbon.
Directions: Fly to Egypt, somewhere along the Nile, preferably, and then travel back in time 4,000 years.

Vacuole Jars
The grains, prepared bread, spices, meat, and drinks that the ancient egyptians ate were stored in clay jars or pots to be used later. Just like the vacuoles of the cell store food, water, and energy, the ancient egyptians' pots stored their food and water (energy) to be used later. In animal cells, vacuoles are numerous and not large and singular like in plant cells, just like the Ancient Egyptians' jars and pots.
Golgi Apparatus
The marketplace is a timeless representation of civilizations past, and Egypt is not exempt from this long-standing tradition. The cities of Ancient Egypt always had some form of a marketplace in which goods and items would be finally packaged to be distributed in some way or other throughout the city. The golgi apparatus is responsible for packaging, modifying, and sorting proteins, lipids, and other macromolecules for distribution throughout the cell and for secretion. The marketplace functions just like the golgi apparatus in that it packages and sorts together products and commodities that are to be dispersed throughout the cell.
Smooth Endoplasmic Reticulum
Here are the ancient egyptian builders seen in history books; they could be farmers, slaves, or paid laborers. They would build homes, pyramids, palaces, and city walls. One of the smooth endoplasmic reticulum's major functions is to synthesize lipids, which are found all over the cell; they create the elements needed for the cell membrane and the organelles and their various membranes. Just like the smooth endoplasmic reticulum creates the components needed for the compositions of organelles and the cell membrane (essentially almost the whole cell), the builders create the elements that make up the town, they build the city gates and all the buildings, the whole city.
Mitochondria

The mitochondria of a cell are responsible for converting energy into forms that are usable for the cell. In the same way that the mitochondria generates energy for the cell by converting energy into forms that are usable, ancient egyptian farmers grew crops from unusable seeds to usable forms that provided energy for all the people of the city.
Cytoplasm
Wherever you stand, as long as it is outside of the pharaoh and his palace, is the cytoplasm. The cytoplasm in a cell is defined as the area outside of the nucleus, the jelly-like fluid that provides structure and contains all the organelles. The area surrounding the palace and organelles parallels the cytoplasm in that it provides structure for the cell and is the space that holds all the components of the city, excluding the royal palace and pharaoh.
