Tissues, which are groups of cells with similar structure and function, are more intricately organized and diversified in complex animals to support their specialized organ systems, whereas in plants, tissues primarily serve functions related to growth, support, and nutrient transport.

The diverse feeding methods and active locomotion of animals necessitate highly specialized and localized organ systems to fulfill various physiological functions efficiently.

Animals, with their active locomotion, require organ systems tailored for mobility and rapid responses to stimuli, whereas plants, with their sedentary existence, prioritize structures suited for nutrient absorption, photosynthesis, and structural support.

Complex animals exhibit a higher degree of specialized and localized structural organization within organs and organ systems compared to complex plants.

The growth pattern influences the organization of tissues and organs in both plants and animals, ultimately determining their structure and function. In plants, localized growth regions and meristematic tissue contribute to their ability to grow taller or wider, while in ...
