Comparison of Starch Content Among the Selected Crops: Gabi/Taro (Colocasia Esculenta), Sweet Potato (Ipomea Batatas) and Potato (Solanum Tuberosum)

Wheat and sugarcane are the leading crops, followed by barley, oats, rice, potatoes, cotton, sunflower seeds, and tomatoes. Fruits include grapes, primarily for wine, and oranges, apples, pineapples, and bananas.

How do different concentrations of sucrose solutions (0M, 0.2M, 0.4M, 0.6M, 0.8M, 1M) affect the mass of potato cores when in sucrose solution?

The graph above indicates that as the concentration of sucrose solution (%) is increased, the percentage change in mass decreases, thus it can be supposed that there is a negative correlation between the sucrose concentrations and the mass of potato cubes. It is also apparent from the graph above that an error has occurred during the 15% sucrose trial as it appears as an outlier also it can be estimated from the graph that approximately10% sucrose solution is the isotonic condition as there is no big change in mass.

Hypothesis: I think that the potato will absorb more starch than the sweet potato and they will both absorb relatively similar amounts of water.

An investigation to find the water potential of potato and carrot tubers in a sucrose solution, of concentration 0.00 – 0.50Mol, over a 24 hour period

Overall the mass of the potato slice for the groups went down during the experiment. The ranges of weight change warried from around 0.2 to 0.3 grams

The purpose of this lab was to find the water potential and osmolality of potato cores after being soaked in NaCl and sucrose solutions and to compare them to each other and the expected water potentials and osmolalities from the literature. We did this by weighing potato cores, soaking them in the NaCl and sucrose solutions, and then weighing them again. This information was used to find the percent weight change of the potato cores. The potato core’s water potential mean for sucrose was -9.86 bars and for NaCl it was -10.72 bars. The osmolality that produced zero weight change in potato cores for sucrose was 0.401 and for NaCl it was 0.439. Our experiment found that the there was no significant statistical difference in the water potential and osmolality of the potato cores soaked in the sucrose and NaCl solutions.

The terrible conditions for rice farming caused prices to increase and more deaths. For rice farming to be productive after major floods killing millions of people, new farming methods such as terraces to contain rain water spread to the rice. These terraces were only made because of the countless trees cut down during the nineteenth century. However, the COlumbian exchange provided population increase for other Asian countries due to potatoes, a plant used by those living in the Andes raw, and cooked, for food and for string. All the basic nutrients are provided in this starch, which allowed life expectancies to grow as well as

Since the beginning of agricultural farming, farmers have utilized processes of selection and sorts of “cross-breeding” in order to improvise upon the quality of the crops that they farm. The process of selection consists of a very systematic means of selecting crops and plants that have fertilized in a superior mode than that of sister plants from the same crop. The utilization of these superior crops helps to ensure more consistent plants and crops that reflect that of the superior selection. Crop selection may also refer to the specific types of crops chosen for agricultural farming. These selections are based on the simplicity of farming that crop and it’s profitability (Bareja, 2011). “Cross-breeding” in farming and agriculture consists of the

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

The various tubes we tested in the spectrophotometer contained different combinations of bean extract, DPIP, phosphate buffer, malonate, and succinate. Tube 1 did not contain any Malonate, and the absorbance values mainly decreased. In

Yams, plantains, green bananas and cassava are the essential staples in Africa. These vegetables are grown and used all over the continent, either on their own or combined with others. Cassava is an important source of dietary carbohydrates in the tropical and subtropical areas of the world, with its roots providing food for over 500 million

To implement Biochemical change there needs to be use of Hybrid seed selection causing increased yields of wheat, rice and maize. Fertilizers are used to increase yield and

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,
