A student says: 'A multicellular organism is just a collection of cells working independently.' Evaluate this statement, referring to the levels of organisation found in a multicellular organism.

A multicellular organism is not merely a collection of cells working independently. In a multicellular organism, specialised cells are organised into tissues – groups of cells with similar structure and function. Tissues are further organised into organs, which are structures made of different tissues working together to perform a specific function. Organs are organised into organ systems, and these systems work together to form the whole organism. Therefore the statement is incorrect because cells do not act independently but are organised at several levels of organisation.
