Briefly discuss and compare structures that maximize surface area for (1) gas exchange and (2) nutrient absorption as well as (3) mechanisms for transport in the following three groups. Angiosperms, Platyhelminthes, Mollusca. Explain functional reasons these structures might vary across the three groups.
