    Potato Osmosis Experiment

    • 610 Words
    • 3 Pages

    the length and mass of the potato when it is put in water and different concentrations of salt? Introduction Osmosis is the diffusion of water molecules from a region of higher concentration to a lower concentration of water molecules (through a partially permeable membrane). If the cell is placed in a higher water potential, water enters by osmosis and if the cell is placed in lower water potential, then the water leaves the cell by osmosis. The experiment we did shows the process of osmosis. How osmosis really works. That is, what will happen to the potato if it is being put in pure water and what will happen if it is being put in salt water? Will the potato become heavier? Will the potato become flexible?…

    Potato Enzyme Experiment

    • 700 Words
    • 3 Pages

    Abstract: In this lab, three variables were tested to discover their effect on the enzyme catalase, taken from a cut and blended potato. The blended potato mixture was strained and put into a centrifuge, the liquid that was in the centrifuge contained the enzyme and remained on ice. The enzyme was placed in test tubes that had varying levels of pH buffers, substrate concentrations and temperatures; the pH, substrate concentration and temperature were the three variables. The data showed that…

    Potato Osmosis In Potato

    There were many observable factors when investigating osmosis in potatoes. Four different solutions were created (distilled water, 1% salt (NaCl), 3% salt and 5% salt. The potatoes were sliced until they were 3cm long, each test tube contained 3 strips of potato cores and a different concentration. The potato strips were weighed and the results recorded. The potato cores were left in each solution for 24 hours. Once the test results were collected the data was averaged and placed into a graph…

    This experiment was focus about osmosis. If solute cannot readily move across the membrane, water will move and tend to balance the solute concentration. In this process, called osmosis, water moves across a membrane from the hypotonic compartment (with a lower concentration) into the hypertonic compartment (with a higher concentration). In hypotonic solution, the concertation of a substance is larger within the cell; the cell gains water to dilute this concertation . in hypertonic solution, the…

    In this experiment, we set out to determine the osmolarity of a potato. In order to do this, we placed potato pieces in seven different solutions of varying sucrose molarity. First, we weighed each potato piece to obtain the initial weight, shown in Figure 1. Then, we split the pieces vertically before placing them in the cubs containing the sucrose solutions. In each cup was a solution of sucrose with a molarity ranging from 0.0M to 0.6M. After placing the potatoes in the cups, we allowed them…

    The results of this experiment show that as the sucrose concentration of the potatoes increases, the potato appearance, shape, and flexibility increase. The qualitative observations show the flexibility of each potato before and after the incubation. The initial observations for the potato slivers were slightly stiff and high in flexibility. After leaving the 10 mL sucrose concentration solution for 45 minutes, the results show an increase in appearance, and flexibility of each individual…

    of the family Solanaceae. Solanaceous plants originated in the new world, and the potato and its relatives were first introduced to Europe in the 16th century. The edible part of a potato, the tuber, is derived from the potato stem. It is rich is starch and has some protein just under the skin. These nutrients are stored in the potato and are intended by the plant to be used for supplying energy and raw materials for new plant growth (Schultz 2006). Diffusion is the movement of molecules from…

    uction The point of this experiment is to examine the result of altering the concentration of sucrose on the rate of osmosis in cylinders of potatoes. This would occur by using like sizes and lengths of potato cylinders and applying them into varying concentrations of sucrose (1%, 5%, 10%, 15%, and 30%) in test tubes then assessing the change in mass of the potato cylinders after. Sustaining all variables unaffected such as the pH, same size, and a constant temperature. Hypothesis: I predict if…

    Abstract: What our problem in our experiment is that distilled water gain mass because there is a higher concentration of solutes while the other solutions contain a lower concentration of solutes. The different types of liquid can affect how the potatoes change or not. Our data shows that Potatoes that were put in the distilled water gained mass while the 5% salt water, 10% salt water, Gatorade, and Coca-Cola lose mass. We also concluded that liquids with high concentration gained mass while…

    The Portrait of Luther Burbank Do you know russet potato derives its name from Luther Burbank? The russet potato is one of Burbank creations, and is the most used potato by the MacDonald’s restaurants. The Portrait of Luther Burbank by Frida Kahlo, is a painting of oil and Masonite created during 1931, this portrait was inspired in the scientist and horticulturist Luther Burbank whom Kahlo represented as one of his own experiments. This Frida Kahlo’s painting shows a man whose feet are a tree…
