Detailed explanation-1: -Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Detailed explanation-2: -If a cell is too large, nutrients simply aren’t able to diffuse through the entire volume of the cell quickly enough. Materials must be able to reach all parts of a cell quickly, and when volume is too large relative to surface area, diffusion cannot occur at sufficiently high rates to ensure this.
Detailed explanation-3: -Explanation: Large surface areas means more of something can pass through it at a particular time. In the cells, if the surface area is large then the diffusion rate is very fast in like amoeba and they can easily obtain oxygen and other important molecules due to this adaptation.
