Why are complex animal bodies more specialized in organ organization than even very complex plants?

Complex animal bodies are more specialized in organ organization than even very complex plants due to the demands of mobility, active interaction, and diverse environmental challenges. Animals require intricate organ systems like nervous, muscular, and sensory systems to navigate, respond swiftly, and adapt to dynamic surroundings. Specialization is crucial for functions such as predation, defense, and complex behaviors. In contrast, while complex plants exhibit specialized tissues, their modular growth and sessile nature reduce the need for elaborate organ systems. Animals’ diverse lifestyles and ecological roles drive a higher degree of organ specialization, reflecting the dynamic and interactive nature of their existence.
