Osmosis and surface area to volume ratio surface area to volume relationships in science osmosis in the balance. The aim of the practical was to observe the rate of osmosis when having the same volume but different surface area potatoes were used during the experiment. The effect of osmosis in potato cells with different concentrations of sucrose solution aim: to test the effect of different concentrations of sucrose solution to osmosis in a potato cells by putting potato pieces in test tubes of water containing different concentrations of sucrose solution. View homework help - worksheet_03 from biology bioloby at oceanside high worksheet name: osmosis in potato tissue during an investigation to determine the effect of surface area on the rate of. Diffusion and osmosis the rate of diffusion, how solute size and concentration affect osmosis diffusion and osmosis investigation i : surface area & cell size .
Measuring the rate of osmosis in potato cells skill area p the surface area over which the osmosis occurs can change the speed at which it happens dramatically . Diffusion and osmosis are affected by the ratio of a cell's volume to its surface area an increase in this ratio means an increase in the rate of diffusion this is because more of the cell's . I have used potato chips, distilled water and sucrose solution to check the rate of osmosis in potato chips when distilled water and different concentration of sucrose solution is added i have used scalpel to cut the potatoes in the size i need and also used to make the surface equal of all the potato chips. The aim of this biology laboratory experiment is to explore the effect of surface area to volume ratio on the rate of osmosis of tap water of solanum tuberosum l solanum tuberosum l, also known as potato, was the selected plant to be tested because it was easy to measure the percentage change in mass due to the osmosis of water into the tissue.
The smallest cube of potato (1x1x1), having a higher surface area to volume ratio, will have the fastest rate of osmosis the smallest cube will have a higher rate of osmosis because it has a proportionally larger amount of surface area (cm2) compared to its volume (cm3). These would include the miscalculation of solutions leading to aninaccurate concentration of nacl as well as the possibility of impurities in the nacl concoction in thefirst place while imprecise cutting of the potato strips could’ve affected the surface area and thusthe rate of osmosis. Surface area to volume ratio and the relation to the rate of diffusion aim and background this is an experiment to examine how the surface area / volume ratio affects the rate of diffusion and how this relates to the size and shape of living organisms.
More the surface area to volume ratio, more is the diffusion surface area to volume ratio, in simple means the size of surface area to the volume of substance that can pass through it at a particular time. An increased surface area to volume ratio increases the rate at which water diffuses through a plant as the surface area to volume ratio increases, the cell becomes thinner allowing for a shorter diffusion pathway. Osmosis and diffusion potato lab mitosis lab (root tip) this shows that surface area yhad a great effect on the rate of thr reaction and rate of diffusion since . Here are the possible variables (listed below): - the width and length give different surface areas which change the amount of osmosis performed by the plant (bigger surface area = more osmosis and vice versa) different vegetables have different concentrations of solution inside temperature-high temperatures give a faster rate of osmosis . Sample lab report- potato osmosis - download as pdf file (pdf), text file (txt) or read online affected the surface area and thus the rate of osmosis which .
Osmosis is the process by which a liquid moves through a semi permeable membrane several factors affect osmosis including temperature, surface area, difference in water potential, pressure and concentration gradient osmosis occurs when there is a high solute concentration area on one side of a . Surface area does not really affect temperature it affects heat transfer a car's radiator has thousands of fins that increase the surface area to increase heat transfer between the air and . Initial discussion of why the surface area to volume ratio is important on the cellular level and a brief description of osmosis and diffusion. Factors affecting the rate of osmosis temperature - the higher the temperature, the faster the movement of water molecules across the semi permeable membrane surface area - the larger the surface area, the more space for the molecules to move easily across the smaller the area, the more restricted the movements of the molecules and the slower . Concentrations of solutions in osmosis, the surface area and increases to the rate of osmosis 1 potato is saturated and water molecules move at maximum rate of.
Diffusion(and(osmosis(lab((part(1:(surface:area:to:volume(ratio(andcell(size( background(cellsizeandshapeareimportantfactorsindeterminingtherateofdiffusion . The effect of surface-area-to-volume ratio on the rate of diffusion hold a discussion on diffusion, osmosis, and associated concepts such as kinetic energy and. Diffusion and osmosis lab introduction: 1) the relationship between the rate of diffusion, volume and surface area is that the surface area of a subject somewhat correlates with the volume of the object. To investigate the effect of surface area on osmosis in potato tissue hypothesis: the larger the surface area of the potato, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger.
The effect that the surface area of an object has on the rate of diffusion can be investigated using a potato and a digital scale (accurate to 001 g) peel the potato, and cut it into 2 cubes, each about 2 cm on a side. Cell surface area experiment posted on may 1, using a scalpel we cut up cubes of potato in the following sizes: 05 cm osmosis and diffusion investigation.
