<span> Many cells have specialized shapes that help accomplish the task of absorbing, excreting large amounts of materials. One important factor cell design for exchanging materials efficiently is to have a relatively large surface area compared to the volume of the cell. An intestinal epithelial cell, for example. Instead of being a large round blob, it is long and stretched out to have a large surface area where absorption and excretion can occur. I hope this helps.</span>
