A cell with two complete sets of chromosomes is called what?

• A. Haploid
• B. Diploid
• C. Monoploid
• D. Polyploid

Answer: (B)

Having two complete sets of chromosomes means the cell is diploid. This is written as 2n, reflecting one full set from each parent. In many organisms, somatic (body) cells carry two copies of each chromosome and form homologous pairs, which is why they’re diploid. Gametes, by contrast, are haploid (n) and contain only one set. If a cell had more than two sets, it would be polyploid (like 3n or 4n); monoploid is a term used in a few contexts to mean a single set. So the term that describes a cell with two complete chromosome sets is diploid.
