In biological terms, what describes how the parts of an organism work together to support its life?

• A. Balance
• B. Structure
• C. Function
• D. Structure and Function

Answer: (D)

Parts of an organism work together because the way they are built (structure) enables what they do (function). The structure is the anatomy—the organs, tissues, and their arrangement. The function is the job each part performs to keep the organism alive, like a heart pumping blood, lungs exchanging gases, or bones providing support and enabling movement. When you look at how a heart is shaped with chambers and valves, you see why it can pump efficiently; when you consider lungs with branching airways and tiny alveoli, you see why gas exchange is effective. The two ideas are linked—the design of the parts makes the activities possible, and those activities rely on that design. Balance is about stability, but it doesn’t capture how the parts’ design and their activities work together. Structure and function together describe how the parts of an organism cooperate to support life.
