Multiple Choice

Why do multicellular organisms need specialized cells?

To perform specific functions necessary for the organism's survival

To reduce the complexity of the organism's overall structure

To increase the organism's size without any functional benefits

To ensure that all cells have identical roles and structures

Verified step by step guidance

Understand that multicellular organisms are composed of many cells, each with specific roles that contribute to the organism's overall function and survival.

Recognize that specialized cells allow for division of labor, where different cell types perform distinct functions, such as nerve cells for transmitting signals and muscle cells for movement.

Consider how specialization increases efficiency, as cells can become highly adapted to perform their specific tasks more effectively than if all cells were identical.

Acknowledge that specialization allows for greater complexity in structure and function, enabling multicellular organisms to grow larger and adapt to various environments.

Realize that the presence of specialized cells does not mean all cells have identical roles; rather, it ensures a diverse range of functions necessary for the organism's survival and adaptation.
