In multicellular organisms, specialised cells form tissues, tissues form organs and organs form systems. Each structure performs particular functions efficiently. This division of labour improves coordination, reduces workload on individual cells and enables organisms to perform complex life processes successfully.
How is the division of labour at various levels of organisation in multicellular organisms correlated with their structure and function?

Multicellular organisms show division of labour through organised levels like cells, tissues organs and organ systems. Each structure is specialised for a particular function. For example, muscles help movement while nerves control coordination. Their structures suit their functions perfectly. This organisation increases efficiency, improves coordination among body parts and helps organisms perform complicated activities necessary for growth, survival and reproduction.
