At 12,000 feet above sea level, in the Andes Mountains of South America lies the origins of our versitale vegatable, the potato. Around 4,500 years ago is when Archeologists estimate that the Inca of Peru began propagating the earliest forms of potatoes. These some what ancient forms of potatoes were small with purple skins, yellow flesh and carried a dense and bitter taste.

The potato could be served baked, boiled, roasted, fried or made into soups, pancakes, dumplings, souffles, pies and even bread! The potato adapted easily to the cool and damp climates of Ireland, Germany, Poland, Russia, Scotland, England, the Netherlands, Belgium, and Scandinavia. And now approximately 3,000 different types of potatoes are grown in America today! In fact, the potato affected Ireland so much that the population expanded from 3.2 million in 1754 to 8.2 million less than a century later. Now China has become the largest sweet potato producer ever, the potato went national faster than Justin

However, there are also some errors in this experiment. Firstly, the potato pieces were not exactly the same size despite the care taken to cut them. A solution to this would be to use a form cutter, which would cut exactly equal shapes. Secondly, the temperature is not exactly a constant variable as it fluctuated throughout the experiment as the test tubes were even put in a refrigerator with a much lower temperature than in the room. A solution for improving could be to place the test tubes into an electric cooler in the beginning to make the temperature stable and put potato pieces when the test tubes are in the cooler. Also, errors could be decreased by using a more precise beaker. Finally, repeating the experiment several times would allow as to take the average results and have a more adequate result.

The skin of the potato became very wrinkled and you could see a decrease in the potatoes

After China developed a new type of potato that utilizes a technique for growing seed potatoes, the United States sought to make this variety better. After rounds of testing and development, the United States refined the Chinese variety of potato making the plants grow more rapidly, which shortens the time taken to produce crop. Also, the variety features virus resistance with the ability for the crop to be easily grown indoors. In October 1995, the first seed potato production was sent and tested in space

Cast the potato cylinders 5. Place all seven potato samples in a petri dish, and keep them close to avert their drying out. 6. Remove a cylinder from the petri dish and place it between the pleads of paper 7. Weight to nearest 0.01g on the aluminum sheet on the balance.

The sides of the potato are not flatten which means have to take precaution while cutting down the sides of the potato to make potato chips therefore use a potato tile to make the experiment safe.

Looking at agriculture, fruits and vegetables, one of main vegetables that are great to humankind, is potatoes. Potato’s play an important role in the world, not by just giving nutrients to human bodies. For example some scientists have a theory of using potatoes to survive on planet Mars in the future (Reader, 2009). Yet not many people know about how the potato affected many countries and where did the potato started to grow. Knowing the basics and history of potatoes can really influence the thought of when someone is eating a French fried potato. Going back to its history, the potato first settled in southern Peru, then causing the destruction the Irish Potato Famine, and potentially ending in future in another planet.

Then wrap copper wire around each penny a few times. Use a separate piece of wire for each penny. Put the pennies in the slits of each potato halve.

Time is of an essence in this step because we need to avoid the oxidization (i.e. turning brown) of the potatoes, which could adjust the effects of the experiment. The potato used for this experiment turned into of the white species. We used a cork borer to cut out 6 plugs of potato and eliminated all skin from every plug. We then weighed every plug to get a weight among 6-7 grams, we had to reduce some of the potatoes to make certain each plug weighed near the identical weight. We positioned all plugs on a paper towel to hold specimens and place clean.

We used with distilled water for the control and increased the molal sucrose in each solution by 0.1 up to 0.7 molal sucrose. Our TA's cut out sixteen Solanum tuberosum (potato) pieces with a cork borer. They measured about 4 cm in length. We then weighed two potato cylinders at a time and set them inside each solution. To keep the moisture in, we covered them with a wet paper towel.

You will use a combination of dirt and hay to make your spud towers. Layers will be added as potatoes start to grow. Just make sure to wait until you see leaves before adding more layers. Simply tip over all towers to dig out all the potatoes when they are ready

The potato was first cultivated in Peru around 8,000 B.C to 5,000 B.C. Spanish Conquistadors conquered Peru, discovered the potato, and then carried them back to Europe. About 40 years later, the potato spread across all of Europe. Sir Walter Raleigh introduced potatoes to Ireland, and the crop became a successful staple for the Irish Population. Agriculturalists in Europe found potatoes easier to cultivate than other staple crops, such as wheat and oats. It was also discovered that potatoes contained most of the vitamins needed for human sustenance. The potato was the perfect plant to survive off of throughout all of Europe, especially

The potato seems to us today to be such a staple food that it is hard to believe that it has only been accepted as edible by most of the Western world for the past 200 years. Our story begins thousands of years ago, in South America—Peru,

We got the following total of the all factors (i.e. Labour Attitude, Potato Quality, and infrastructure) from the locations: -
