Question

How is the division of labour at various levels of organisation in multicellular organisms correlated with their structure and function?

Answer 1

In multicellular organisms, division of labour refers to separate portions performing specialised duties, which is strongly related to their structure.

• Cells are specialised in shape and structure to perform certain jobs, such as nerve cells that transmit impulses.
• At the tissue level, comparable cells band together to execute a common function, such as muscle tissue that moves.
• At the organ level, various tissues join to form organs such as the heart, which pumps blood.
• Organs work together at the system level, such as in the digestive system.

Thus, at each level, structure is customised to function, enabling the organism's efficient operation.
