So in my biology 1 class, we did a lab called why are cells so small it had to do with surface area:volume ratio i've looked at other answers on ya, and they all had to do with this ratio what does it mean do cells want to be large do they want a large surface area. All biological cells require the transport of materials across the plasma membrane into and out of the cell by infusing cubes of agar with a ph indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells then, by observing cubes of different sizes, you can discover why larger cells might need extra.
