In terms of maximizing diffusion, the most effective cube size that i tested was the smallest cube which was 1cm by 1cm by 1cm this size was most effective at maximizing diffusion because of its surface area to volume ratio (sa:v) the smallest cube had the greatest sa:v ratio. Free essay: [type text] [type text] [type text] _an experiment on the effect of surface area to volume ratio on the rate of osmosis of solanum tuberosum l_. Surface area and volume using different volume agar cube lab report essay sample experimental method: agar jelly cubes are used as samples of cells. Lab report = surface area to volume ratio effect on diffusion uploaded by irena sionek 17092014 1 irena sionek 2ib difussion in agar cubes – lab report research question what is the effect of surface area on volume ratio on the rate of diffusion of pigment from the agar cube measured by percentage volume of diffusion over time background diffusion is a process of.

Backgroundcells rely on the diffusion process to gain nutrients and to dispel waste because of this, the surface area to volume ratio of cells is very important as a object becomes smaller, its surface area to volume ratio becomes greater allowing fa. Aim: to determine the relationship between surface area and volume ratio of a phenolphthalein impregnated agar block, and the rate of diffusion into the block description: diffusion is the passive movement of particles from high concentration to low concentration it is a very slow process so therefore the smaller the cell it is more efficient [. Students have to calculate volume, surface area, and sa:v ratio students then immerse each block in common household white vinegar either in small beakers or in more tray tops agar turns yellow in acid you can easily see the blue core disappear as diffusion takes place students time until blue completely disappears helps to put beakers on white paper as a background you'll notice that.

What happens to the surface area to volume ratio of a cell as it grows 2 when one cell divides into 2 equal parts, what happens to the surface area to volume. Essay on diffusion with surface area to volume ratio volume of cube: s3 s = 7cm s3 = (7cm x 7cm x 7cm) = 343cm3 2 compute the volume of a cuboid (also known as a rectangular prism). Difussion in agar cubes – lab report research question what is the effect of surface area on volume ratio on the rate of diffusion of pigment from the agar cube measured by percentage volume of diffusion over time. Surface area and volume using different volume agar cube lab report essay to improve the reliability of the answers, experiment with a larger sample is to use agar blocks to investigate the effect of surface area to volume ratio on the rate of diffusion another factor that directly affects the rate of diffusion is the surface area to essays / projects are typically greater than 5 pages in. The cell with the medium surface area to volume ratio diffused the fastest, but also was cut from a different cube of agar the cubes may have been poured at a different point or have contained a different phenolphthalein concentration, which would have affected the diffusion rate the second experiment was greatly affected by how well the knots were tied on the dialysis tubing any of the.

Surface area to volume relationship using plastic cubes finally, we will analyze the diffusion process by finally, we will analyze the diffusion process by graphing. Essay on biology and the properties of gas exchange surfaces 1215 words 5 pages show more properties of gas exchange surfaces alveolus – air sac in the lungs • hundreds of thousands in lungs • increase lungs sa sa:v ratio = surface area volume diffusion 05 cm cube – 2mm cubed of non dyed agar 1cm cube – 5mm cubed of non dyed agar 2cm cube – 18mm cubed of non dyed agar diffusion. As the cube size increases or the cell gets bigger , then the surface area to volume ratio - sa:v ratio decreases when an object/cell is very small, it has a large surface area to volume ratio, while. 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.

In comparison, in the same amount of time, the largest cube, with a 2:1 surface area to volume ratio and the medium cube with a 4:1 ratio, were not able to thoroughly diffuse when cells grow to a certain size, they frequently divide to form two new smaller cells. Requirements depends on the surface area to volume ratio (sa/vol ratio) as organisms get as organisms get bigger their volume increases by the cube of their size, whilst their surface area. 4:1 will have the best chance at maximizing diffusion because the greater the ratio between volume and surface area, the smaller the cell is, and the less chance it has to contain dead parts which maximized the effectiveness of the cell.

- The pink agar cubed immersed in hydrogen chloride (hci) had a faster process of diffusion than the clear agar cube immersed in potassium manganese (kimono ) conclusion: the reason cells are so small is because it facilitates the diffusion as seen in the experiment, diffusion is more efficient when there is a bigger surface area to volume ratio this process is essential for every cell to.
- The aim of this experiment is to explore the relationship between surface area to volume ratio and rate of exchanging materials cells are the structural and functional unit of all living organisms they grow, take in nutrients and get rid of wastes through the process of diffusion diffusion is the spontaneous movement of a substance from high to low concentration it is how many substances.

As the cube size increases, the surface-area-to-volume ratio decreases (click to enlarge the table below) the vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly. (the formula for the surface area of a cube is 6 x s2, and the formula for the volume of a cube is s3, where s = the length of a side of the cube) which of the following cube-shaped cells would be most efficient in removing waste by diffusion. Practical for agar block diffusion with acid user description: recieved an a+ abstract purpose and procedure- the purpose of this experiment is to determine the effect of surface area to volume ratio on agar blocks in sulphuric acid (h₂so₄.
