The prefix troph/o is associated with which concept?

• A. Movement
• B. Development
• C. Growth
• D. Nourishment

Answer: (B)

The main concept being tested is what the prefix troph/o indicates in medical terminology. Troph/o comes from a Greek root meaning nourishment and the idea of feeding tissues so they develop and mature. In terms you’ll encounter, this prefix points to how tissues are nourished and how they grow and develop over time. That connection to the process of maturation and formation makes development the best fit among the options. Movement is tied to mot/o, not troph/o, and while nourishment and growth are related to troph/o, development best captures the ongoing process this prefix signals.
