The difference in organ system design between plants and animals primarily stems from their distinct evolutionary histories and ecological needs. Plants, rooted in place, prioritize structures like roots, stems, and leaves for absorption, support, and photosynthesis. In contrast, animals, mobile and heterotrophic, have evolved complex organ systems like circulatory, nervous, and digestive systems to support movement, sensation, and energy acquisition from external sources.

The difference in organ system design between plants and animals arises from their distinct life strategies and adaptations. Plants, being stationary, have specialized systems for resource acquisition and support, such as roots, shoots, and vascular tissues. Animals, being mobile, have complex systems for movement, digestion, respiration, and circulation. These differences reflect their unique interactions with the environment and methods of survival and reproduction.
