Explain why multicellular organisms require specialized exchange surfaces and transport systems, focusing on the limitations of the surface area to volume ratio.
Recognize that single-celled organisms possess a large enough surface area to volume ratio to rely solely on cellular diffusion.
Describe the hierarchical organization of multicellular organisms from specialized cells to tissues, organs, and organ systems.
Evaluate how the effectiveness of exchange surfaces is maximized through adaptations such as large surface areas, thin membranes for short diffusion paths, and efficient blood supply or ventilation.
Calculate and accurately compare the surface area to volume ratios of different shapes or organisms.
