Root Explanation

Haploid is formed from "haplo-" (from Greek "haploos", meaning single or simple) and "-id" (a suffix used in biology to denote a condition or state). The word "haploid" refers to a cell or organism that has a single set of chromosomes, hence indicating a simple or single condition of genetic material.

Memory Tip

Think of 'haplo-' meaning 'single' — this helps you remember that 'haploid' refers to a single set of chromosomes.
