7. STRUCTURAL ORGANISATION IN ANIMALS

The structural organization of animals emphasizes the division of labor across cells, tissues, organs, and organ systems to ensure survival and functionality. In multicellular organisms, basic tissues combine to form organs that conduct specific functions. Frogs, as members of the class Amphibia, serve as an example to understand organ systems, including their distinctive morphology and anatomy, which are essential for their survival in varied environments.
