Which term refers to a specialized part of a cell that performs a specific function?

• A. Organelle
• B. Nucleus
• C. Spinal Cavity
• D. Regenerative Medicine

Answer: (A)

Organelles are the specialized parts of a cell that perform specific functions. Inside a cell, these tiny structures each have a job, like mitochondria producing energy, ribosomes making proteins, or lysosomes breaking down waste. The term that covers all of these specialized components is organelle. The nucleus is one example of an organelle, but the question asks for the general term, not a single part. Spinal cavity and regenerative medicine are not cell components—one is a body space, the other a medical field—so they don’t fit.
