List everything you would expect to see on a dairy farm?

2. Cell Dairy Farm
Another way to get students excited about creating a dairy, ask them if they are played Farmville on Facebook. Explain to the students they will be create their own farmville today.

3. 1. Pens and corrals
The endoplasmic reticulum (ER) is a series of interconnecting flattened tunnels which are attached to the outer membrane of the nucleus. The ER is the transport network for molecules targeted for certain modifications and specific final destinations.
Explain to students that on a dairy the pens and corrals are interconnecting and serve as a network throughout the dairy. In the cells, the endoplasmic reticulum has a similar function. The goal of a cell is to make protein and the goals of a dairy is to make milk (which is a protein!!). Later in the lesson you will share with the students that the cows are like the ribosomes because they too make proteins. Ribosomes are attached to the ER and free floating in the cells just like the cows are housed in the pens and corrals.

4. 2. Farm Gates
The cell membrane is found directly inside the cell wall in plants.  It allows things to pass into and out of the cell. Materials like food and oxygen are kept inside the cell. Waste products and excess water are allowed to leave. In that way the cell can maintain correct conditions inside the cell regardless what the conditions may be outside the cell. This is known as a process called homeostasis.
The main function of the cell membrane is to allow things to pass in and out of the cell. The main function of a farm gate is to keep some things off the dairy and allow some things to come

5. 3. Outer Fence
In a plant cell the cell wall is found outside the cell membrane. In an animal cell, the cell membrane forms the outer covering of the cell.
The cell wall is made of a tough material called cellulose and acts like a fence, keeping the cell safe from the environment. It forms a barrier between the living material inside the cell and the environment outside.
The cell wall also provides support for the cell. Animal cells, unlike plant cells, do not have a rigid cell wall.

6. 4. Dairy Cows:
Ribosome
The ribosomes are found on the endoplasmic reticulum and floating in the cytoplasm. The ribosome is the protein factory of our cells. Without protein we wouldn't have cell membranes, enzymes, or substance in our bones, but the real construction site of the cell creates the ribosomes!
The dairy cows main function is to produce milk. Just like the ribosomes synthesize proteins.
Protein

7. 5. Dairy Products Processing Plant:
Golgi Apparatus
The Golgi apparatus is a bit like a factory’s customization shop, where the finishing touches are put on products before they are ready to leave and “shipped” to their final destination. The Golgi apparatus attaches carbohydrates and lipids to them.
The Golgi apparatus packages proteins before they leave the cell just like the Processing Plant packaging the milk products prior to shipping out.

8. 6. Solar Energy Panels
Chloroplasts, found only in plant cells, are green because they contain chlorophyll. Chlorophyll is what captures the energy of the sun, which can then be used to help produce food for the plant cell in the process of photosynthesis.
Both the chloroplasts and solar energy panels use the sun to make energy.

9. 7. Farm Office:
Nucleus
The nucleus is the control center of the cell, acting like the "brain." The nucleus is the largest organelle in a cell and can usually be seen using a light microscope. The nucleus contains the DNA of the cell - the genetic code which allows the cell to reproduce and which allows it to make all the proteins it needs to carry out the normal business of living.
Control center of the farm is the farm office, just like the control center of the cell is the nucleus

10. 8. Farm Records: Nucleolus
Dense place inside the nucleus where the DNA is stored

11. 9. Fence Around Farm Office:
Nuclear Envelope

12. 10. Dairy Manure Digester:
Mitochondria
The mitochondria are often called the 'power stations' of the cell. The reactions involved are very complex but, put very simply, the mitochondria burn food molecules to release energy. This energy is used by cells to do work. This work may be building new molecules which have a particular function in the body, or it may be to produce movement (muscle cells, for example).
They collect the methane given off by fermenting cow manure and use it to generate electricity. The procedure is relatively simple: manure is stored in huge tanks — anaerobic digesters — which are deprived of oxygen and kept at temperatures of 100°F. The conditions are designed to let anaerobic bacteria thrive and do the work of breaking the manure down. The large volume of "biogas" released — which contains about 90% methane — is piped to an engine which burns the gas and uses the heat energy to generate electricity. The leftover manure is compressed; fluid is drained away and used as fertilizer; and the solids are dried out and used as bedding for the herd and compost.

13. 11. Tractor:
Lysosomes are small organelles filled with enzymes. Lysosomes also help break down organelles that outlived their usefulness. Lysosomes perform the vital function of removing debris that might otherwise accumulate and clutter up the cell.

14. 12. Silo and Water Trough:
Vacuoles are used to transport and store nutrients, waste products and other molecules. The presence of a vacuole enables plant cells to grow larger than animal cells - the expansion of a fluid filled space is a lot less costly in terms of energy expenditure than expansion of a cell full of organelle-containing cytoplasm. Vacuoles are also used for storage of substances which the plant needs, but which may be toxic to the rest of the cell.

15. 13. Pasture and Open Space
The cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cell.
