Root Explanation
Cryopreserved → It is formed from "cryo-" (from Greek "kryos", meaning cold) and "preserved" (from Latin "praeservare", meaning to keep safe or protect). The word "cryopreserved" refers to biological materials that are kept safe by being stored at very low temperatures.
Memory Tip
Think of 'cold' ('cryo-') being used to 'keep safe' ('preserved') — that's why cryopreserved means kept safe by being stored in cold conditions.
