AT1 Bilology

Biology AT1 Coursework What I am going to do For my biology AT1 I am going to how the concentration of weewee 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 pastures of voices of white potato into different concentrations of piss and sucrose solutions. I will weigh each potato before and by and by each investigate so that I can maneuver the in cant all over in each piece of potato by subtracting the come out weight of the potato from the final weight after the experiment has been conducted. Explanation of Osmosis Osmosis is a kind of dispersion involving pissing. Osmosis take place when ii solutions (with ate least integrity solution containing water molecules) are separated between a partially porous membrane which is a material that water molecules that are nice can easily pass by but sizeable molecules like sugar molecules are too big to volley 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 solve continues until both solutions have reached an equilibrium and so are cost in concentration.

Preliminary Experiment forward I carryout my undeviating Experiment, I am going to do a front experiment on a figure that I am going to keep the same in my real experiment. My precedent experiment is to tally what size of piece of potato I should use in my real experiment and also to see what roughly should happen in my real experi! ment so that I can compare the two to make genuine there are no study differences between them.
