performed to calculate what effect salinity had on the rate of osmosis tested with the use of potatoes. Using the method that is written above, we tried to determine at what salinity solutions osmosis had the most notable results at. What can be viewed from the results and graph of these results, we can determine that at 5% and 10% solutions, the higher percentage of the potato was affected by osmosis. The purpose of this experiment was to study osmosis, with the use of potatoes. As there was a recorded
Osmosis Lab Report BIO 2101-02 Jasmine Monger (+Tayshondalyn Huntley, Brandi Burke, Jasmine Vann) Dr. Carly Kemmis December 5, 2014 Introduction Osmosis is the movement of water from a low concentration to a high concentration across a different permeable membrane. When talking about osmosis three terms are usually connected to it or heard during the same time. Those three terms are hypotonic, hypertonic, and isotonic. These three terms can be categorized as the tonicity, amount of solute
Brookelyn Snider Biology Lab 261 The Effect of Diffusion and Osmosis on White Potato vs. Sweet Potato Introduction: The purpose of this experiment was to develop an understanding of water—solute balance. In this experiment, sweet potatoes and white potatoes were used as model systems. (Bio 261 Lab Manual) Diffusion is the movement of particles from an area of a higher concentration to one of a lower concentration. In this experiment this would be the movement of particles
experiment, it was believed that Increasing the concentration of NaCl will increase the rate of osmosis. The results, evidently supported the hypothesis by the changes in the potato cylinder mass due to the concentration of solutes. The increase in mass is due to the lower concentration salt present in the potato cylinder. The theory supporting this observation suggests that the potato cylinder was submerged in a hypotonic solution (lower solute concentration). As this sample was in distilled water, the
Criterion B: Osmotic Potential in a Potato Introduction Context: The purpose of my scientific investigation is to investigate “the effects an epidermis has on the osmotic potential of a potato”. This is because, I have observed that a lot of food chains around the world choose to take the epidermis off the potato while soaking it in water. Whereas, other food chains choose to keep the epidermis on the potato while soaking it in water. The aim of the test is to determine which one of these practices
The data that has been derived from the experimentation supports and substantiates the hypothesis that the mass of potato stripes decrease when they are put into solution with greater concentration and that the mass of potato stripes increase when they are put into a less concentrated sucrose solution or a dilute solution. This is demonstrated on the scatter graph above with a downward sloping line of regression, which indicates a negative correlation. The largest percentage mass change was seen
BIOFUELS Two problems roused the world’s concern in recent years. One is energy crisis caused by the squandering of petroleum fuel. Second problem is environmental problems such as greenhouse effect, global warming, etc. To deal with such problems, renewable sources, utilization technology and bioenergy production technology have been developed. Bioethanol as one of the biofuel can be blended in different proportions in automobiles with gasoline. Biobutanol is also a new biofuel (Liu, Wang, & Zhang
