Essay on biology lab report part 1- testing for diffusion: a guided activity summary of experiment: the point of the experiment was to see how diffusion works and what it effects. Osmosis is the movement of water from an area of high concentration to an area of low concentration across a semi permeable membrane an osmotic system is established when a semi-permeable membrane is placed between two solutions in this biological systems context, osmosis is the exchange of water between the potato cell and the surrounding medium of varying sucrose concentrated solutions.

Gcse biology: osmosis in a potato aim to investigate the effect of placing a piece of potato in a given strength of sugar solution prediction i predict that, as the solution becomes more concentrated the more the cell will shrink, as the water, of higher concentration inside the potato cells, flows down a concentration gradient into the solution, which has a lower concentration of water. Biology bio3t/p14/tn unit 3t as investigative skills assignment the effect of concentration of blackcurrant squash on osmosis in potato cylinders different concentrations of blackcurrant squash they will be provided with five concentrations of blackcurrant squash and potato cylinders the candidates will prepare the cylinders, weigh. Observing my results, i can see that the potato that weight 222g at 0% of black currant squash has the highest mass between the other potato masses because in the potato strip, the osmosis from outside the cell enters the vacuole to dilute it as the cell since has stronger solution in it, thus the cells will become turgid as they are full of. Its about blackcurrant squash concentration and change in mass of the potato make sure you know how to calculate the percentage change 0 reply.

Potato chip: this will help me justify if osmosis is occurring i have used potato chip to help me justify if osmosis as it is a semi-permeable cell the length, width and mass of all the potato chip used in the experiment are to be kept same. Thus it forms holes, disrupting the membrane of the beetroot core which essentially prevents the betacyanin pigment from leaving the cell also, when exposed under heat, the cholesterol, glycolipids and phospholipids expand, putting pressure on the membrane from inside. What is the effect of concentration of blackcurrant squash on osmosis in chipped potatoes place potato on a paper towel on the lab bench when using radish or potato as a source of catalase, lack of uniformity in the surface area of. Investigating the effect of concentration of blackcurrant squash on osmosis in chipped potatoes the purpose of this investigation is: to explore what happens to chipped potatoes in different concentrations of blackcurrant squash.

It’s all actually quite simple really – make 6 concentrations of blackcurrant squash (from 0% to 100%) (oh, and whilst ribena works very well, so does the blackcurrant cordial we tried), put a pre-weighed potato chip into each concentration and leave for 15-20 minutes. Investigating the effect of concentration of blackcurrant squash on blackcurrant squash to explain the outcomes in terms of osmosis collect some potato chips or a potato to cut up cut or trim your chips, if necessary to fit into your small beaker/ boiling tube.
