Diffusion in agar cubes and cellular wasted are transported between living cells calculate the surface area of each cube and the surface area to volume ratio:. The ratio between the surface area and volume of cells biology cell structure and function surface area to volume ratio we can see this with agar cubes that. The most efficient agar cells will be the 64 cubes with lengths of 05cm and a surface area to volume ratio of 1:16 because it has the smallest surfaced area to volume ratio the least efficient one would then be the agar cube with the length of 2cm and a surface area to volume ratio of 3:1 because it has the largest surface area to volume ratio. Home essays agar cubes lab report agar cubes lab report diffusion in agar cubes introduction: all cells as the surface area-to-volume ratio.

You will use agar cubes, which have a high salt content, as cell models how does a cell's surface area to volume ratio limits its size. To diffuse into the agar blocks, explore surface area to volume cubes you constructed represent cells the surface area to volume ratio.

Ratio of surface area to volume = surface area/volume example: a cube 5 cm on each side: surface area = 5 cm x 5 cm x 6 =150cm2 volume =5 cm x 5 cm x 5 cm = 125cm3 ratio = 150/125 = 12: 1 challenge: design a biological model that illustrates how the ratio of surface area to volume ratio affects the rate of diffusion into and out of living systems. The aim of this experiment is to find the how a cell’s surface area and volume ratio if the surface area of the cell and it makes the colors of the cubes. I recently did a biology prac report testing the surface area to volume ratio, involving cell model agar cubes of various sizes the agar cubes contain phenolphthalein, an indicator and an alkaline, sodium hydroxide and the phenolphthalein reacts with sodium hydroxide, giving the agar a pink colour.
