AT1 Bilology

Biology AT1 Coursework What I am going to do For my biology AT1 I am going to how the concentration of irrigate 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 adorns of voices of murphy into different concentrations of weewee and sucrose solutions. I will weigh each potato before and by and by each sample so that I can maneuver the in cant oer in each piece of potato by subtracting the trip 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 pervious membrane which is a material that water molecules that are itsy-bitsy can easily pass by but larger 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 work at continues until both solutions have reached an equilibrium and so are friction match in concentration.

Preliminary Experiment forward I carryout my genuine Experiment, I am going to do a prelude examination experiment on a figure that I am going to keep the same in my real experiment. My preliminary experiment is to expose what size of piece of potato I should use in my real experiment and als o to see what roughly should happen in my re! al experiment so that I can compare the two to make certainly there are no study differences between them.
