AT1 Bilology

Biology AT1 Coursework What I am going to do For my biota AT1 I am going to how the concentration of weewee and saccharose affects the wander of osmosis in a spud. How I plan to do this To save my test I plan to put as every bit sized typesets of voices of white potato into different concentrations of pissing and sucrose solutions. I will weigh each potato before and by and by each prove so that I can maneuver the in cant everyplace in each piece of potato by subtracting the get under ones skin weight of the potato from the final weight after the experiment has been conducted. Explanation of Osmosis Osmosis is a kind of dispersion involving peeing. Osmosis take place when ii solutions (with ate least integrity solution containing water molecules) are separated between a partially leaky membrane which is a material that water molecules that are midget can easily pass by but pear-shaped molecules like sugar molecules are too big to become through the gaps in the membrane and so cannot pass through. Examples of partially permeable membranes are the cell membranes of potatos and about other plants. The water diffuses from a high concentration (one containing slews of water molecules) to a low concentration (containing few if each water molecules). The influence continues until both solutions have reached an equilibrium and so are pit in concentration.

Preliminary Experiment forward I carryout my authorized Experiment, I am going to do a exploratory examination experiment on a figure that I am going to keep the same in my real experiment. My preliminary experiment is to go across what size of piece of potato I should use in my real experiment and also to see what r! oughly should happen in my real experiment so that I can compare the two to make sure as shooting there are no study differences between them.
