To investigate the effect to the potato cells in the different solute concentration water Essay

Water preserve move through the different cells repayable to the difference of wet potentials in the cells. If there is a higher solute concentration in the cell than after-school(prenominal) the cell, the pee exit move into the cell. However, if the concentration of inside the cell is degrade than the out(p)side, water testament not move into the cell. This process is called osmosis. Research motionThis investigation result determine how different pure sugar water lead affect to the mass change of the white potato vine cells using the invention of osmosis. HypothesisI predict that the potato slice in beaker C will gain the most increased mass than beaker B and C. The creator is that since beaker C has a highest concentration among the test beakers, it will affect the most to the potato cells. The movement of water will move actively in beaker C. VariablesIndependent VariableIn this experiment the independent variable will be the sucrose concentration of water. This i s reserveled by using a item inwardness of sugar that we pour into the distilled water. We will do the activity in the solutions with concentration of 0, 0.25, 0.50%. Dependent VariableThe dependent variable will be the coat of potato slices that goes into the solutions. This depends on the various environmental factors during making a slice of potato such as the thickness of core or the peel of potato. Thus it could differ during the experiment. Controlled VariableAnything that can change the yield of this experiment will be the controlled variables. Therefore, we consider to control variables that can be controlled to get the most accurate and authoritative information in this experiment. similarly the purpose of an experiment is to find out the ca employment of the lab and how it affects. Without these variables, it would b e difficult to determine which cause made the effect out of the lab. Water LevelClearly if we have higher level of water in the beaker to make concen trated sugar water, the concentration will be lower than the less level of water. To get the consistent data, we need to control the level of water in the same level possible. Size of CoresWe will use the slices of potato in this lab, and if we have different sizes of potato slices due to the different sizes of cores that we have used to make a slices, the result will be vary as the size gets bigger or smaller. Therefore, during the lab, we need to use the same grapheme and size of the cores. Type of PotatoesIf there ar different types of potatoes, the osmosis that happens to the potato from the sugar water will not be the same. This needs to be controlled by using a same type of potato to get the most accurate data possible. Time of submergenceIf one potato slice has stayed in the solution longer than the separate sets, the data is not reliable because it is not experimented in equal amount of clock time. In order to get the reliable data, we need to measure the time equally a nd record it to the data paper. Size of the petri dishWe need to use the same size of the petri dishes to collect the reliable and accurate data. Different size of the petri dishes will boost or slow down the osmosis in the potato cells. HumidityHumidity near the experiment place will alike affect to the experiment. If the pace is hot and dry, the solution may evaporate short due to the particles inside the solution absorbs the heat. Also when it is cold, the osmosis may not elaborate normally. Due to these facts, we need to control the size of the petri dishes to get the best data possible. Temperature of the solutionsIf the solution As temperature is higher than the solution B and C, it will affect to the speed and rate of the osmosis. In order to get the reliable and best data, we need to control the temperature of the solutions in to equal celsius possible.Apparatus3 different concentrated solutions (0, 25, 50 mol/dm3)BeakersPipettesPotato cores dimensionMeasuring cylinderPet ri dishesBlack penRulerPotato slices surgical procedure1.
