Smaller organisms have a small surface area to volume ratio
|
|
|
The surface area to volume ratio is zero for small organisms.

|
Small organisms have a large surface area to volume ratio
|
Detailed explanation-1: -Small cells have a larger surface area per volume ratio when compared to large cells. hence smaller cells can absorb more number molecules than larger cells.
Detailed explanation-2: -Single celled organisms have a very large surface area to volume ratio, however large organisms on the other hand have a greater volume, with a smaller increase in surface area.
Detailed explanation-3: -Surface Area The plasma membrane surrounding cells limits the rate at which these materials are exchanged. Smaller cells tend to have a higher surface area to volume ratio than larger cells. That is because changes in volume are not linear to changes in surface area.
Detailed explanation-4: -Hence, a Platyhelminth would have the most surface area-volume ratio compared to other given organisms.
Detailed explanation-5: -BEARS/POLAR BEARS A sphere has the smallest surface area-to-volume ratio of any shape. While a one unit cube has a ratio of 6:1, a one unit diameter sphere has a ratio of only 4.84:1.
