Complex multicellular organisms have higher metabolic rates and generate larger quantities of metabolic wastes compared to unicellular organisms. Specialized excretory organs are necessary to efficiently remove these wastes from the body and maintain internal homeostasis, ensuring the organism’s overall health and survival.
Why do complex multicellular organisms require specialized excretory organs?
Share
Complex multicellular organisms require specialized excretory organs because their larger size and increased metabolic activities result in higher volumes of waste production. Specialized organs, such as kidneys in animals, enable efficient filtration, reabsorption, and concentration of waste products. These organs help regulate the internal environment by eliminating nitrogenous wastes, excess ions, and maintaining water balance. The complexity of multicellular organisms demands a sophisticated excretory system to prevent the accumulation of harmful metabolic byproducts, ensuring the organism’s overall health, maintaining homeostasis, and supporting various physiological processes in the intricate interplay of organ systems.
