Compare and Contrast the animal cell to the plant cell - that is, describe how they are alike, and how they are different.
Cell City Analogy
In a far away city called Grant City, the main export and production product is the steel widget. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. The town hall has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced in small shops around the city, these small shops can be built by the carpenter's union (whose headquarters are in town hall).
After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper passports) are allowed outside the city.
Match the parts of the city (underlined) with the parts of the cell.

The Cell Overview
Early Contributions
Robert Hooke - The first person to see cells, he was looking at cork and noted that he saw "a great many boxes. (1665)
Anton van Leeuwenhock - Observed living cells in pond water, which he called "animalcules" (1673)
Theodore Schwann - zoologist who observed that the tissues of animals had cells (1839)
Mattias Schleiden - botonist, observed that the tissues of plants contained cells ( 1845)
Rudolf Virchow - also reported that every living thing is made of up vital units, known as cells. He also predicted that cells come from other cells. (1850 )
The Cell Theory
1. Every living organism is made of one or more cells.
2. The cell is the basic unit of structure and function. It is the smallest unit that can perform life functions.
3. All cells arise from pre-existing cells.
How big are cells?
Why most cells are small has to do with simple geometry more than anything else: specifically the relationship between surface area to volume as a cell gets bigger. First, as a cell gets larger, the volume of the cell increases more rapidly than the surface area if the cell maintains its same shape.
Everything that the cell needs or has to get rid of has to go through the cell membrane, the amount of which relates to the surface area. Therefore, the cell's ability to either get substances from the outside or eliminate waste is related to the surface area. Secondly, how much food and other material from the outside and how much waste the cell has to get rid of, is related to the volume. Therefore, as a cell gets bigger there will come a time when its surface area is insufficient to meet the demands of the cell's volume and the cell stops growing.
Cell Features
Ribosomes - make protein for use by the organism
Cytoplasm - jelly-like goo on the inside of the cell
DNA - genetic material
Cytoskeleton - the internal framework of the cell
Cell membrane - outer boundary of the cell, some stuff can cross the cell membrane. Composed of phospholipids and proteins.
Types of Cells
Prokaryotic Cells
Prokaryotes are very simple cells, probably first to inhabit the earth.
Prokaryotic cells do not contain a membrane bound nucleus.
Bacteria are prokaryotes.
DNA of bacteria is circular.
The word "prokaryote" means "before the nucleus"
Other features found in some bacteria:
Flagella - used for movement
Pilus - small hairlike structures used for attaching to other cells
Capsule - tough outer layer that protects bacteria, often associated with harmful bacteria
Eukaryotic Cells
Eukaryotic cells are more advanced cells. These cells are found in plants, animals, and protists (small unicellular "animalcules"). Protein Production: Ribosomes make protein and send them through the ER to the golgi apparatus, the GA then processes the proteins, tags it and exports it to where the protein is needed. The eukaryotic cell is composed of 4 main parts:
1. cell membrane - outer boundary of the cell
2. cytoplasm - jelly-like fluid interior of the cell
3. nucleus - the "control center" of the cell, contains the cell's DNA (chromosomes)
4. organelles - "little organs" that carry out cell functions
| |Cell Part |Function |
|[pic] |Mitochondria |Energy center or "powerhouse" of the cell. Turns food into useable energy |
| | |(ATP) |
| |Ribosomes |Make protein |
|[pic] |Golgi Apparatus |Processes, packages and secretes proteins. Like a factory. |
|[pic] |Lysosome |Contains digestive enzymes, breaks things down, "suicide sac" |
|[pic] |Endoplasmic Reticulum |Transport, "intracellular highway". Ribosomes are positioned along the rough|
| |Smooth ER - no ribosomes |ER, protein made by the ribosomes enter the ER for transport. |
| |Rough ER - ribosomes | |
| |Nucleolus |Located inside the nucleus, makes ribosomes |
| |Vacuole |Stores water or other substances, plant cells contain a large central |
|[pic] | |vacuole. |
| | | |
| |Chloroplast |Uses sunlight to create food, photosynthesis (only found in plant cells) |
| |Cell Wall |Provides additional support (plant and bacteria cells) |
|[pic] |Microtubules |Part of the cytoskeleton, function in support |
