Quizplus · Accepted Answer

Unicellular organisms have only one cell, and therefore do not possess complex organ systems. They exchange gas, eliminate wastes, and absorb nutrients directly through their cell membranes. They do not require another organism to process these materials for them, as they are able to carry out these functions independently. Humans, on the other hand, have complex organ systems and do not exchange materials directly through their cell membranes.
