Biology AT1 Coursework What I am going to do For my biology AT1 I am going to how the concentration of water and sucrose 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 places of voices of potato into different concentrations of water and sucrose solutions. I will weigh each potato before and by and by each experiment so that I can maneuver the in cant over in each piece of potato by subtracting the start weight of the potato from the final weight after the experiment has been conducted.
Explanation of Osmosis Osmosis is a kind of dispersion involving water. Osmosis take place when ii solutions (with ate least integrity solution containing water molecules) are separated between a partially permeable membrane which is a material that water molecules that are small can easily pass by but large molecules like sugar molecules are too big to fit 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 process continues until both solutions have reached an equilibrium and so are equal in concentration.
Preliminary Experiment forward I carryout my reliable Experiment, I am going to do a preliminary experiment on a figure that I am going to keep the same in my real experiment.
My preliminary experiment is to see what size of piece of potato I should use in my real experiment and also to see what roughly should happen in my real experiment so that I can compare the two to make sure there are no study differences between them.
Preliminary...
