Root Explanation
Polyploid → It is formed from "poly-" (from Greek "polus", meaning many) and "ploid" (from Greek "ploides", meaning fold or layer). The word "polyploid" refers to an organism that has multiple sets of chromosomes, hence many layers of genetic material.
Memory Tip
Think of 'many' ('poly-') layers or sets ('ploid') of chromosomes when you hear 'polyploid'.
