Why is cell specialization essential for multicellular organisms?

• It allows for more efficient energy use.

• It enables different cells to perform specific functions.

• It simplifies the structure of cells.

• It reduces the need for nutrients.

How does the concept of 'form equals function' apply to biological systems?

• All cells have the same form and function.

• The structure of a cell or organ is designed to perform its specific function efficiently.

• Function is irrelevant to the structure of biological systems.

• Biological systems function independently of their form.
