Which term describes a cell containing two sets of chromosomes (2n)?

• A. Haploid
• B. Gamete
• C. Diploid Cell
• D. Geographical Isolation

Answer: (C)

Chromosome number in a cell determines whether it has two complete sets of chromosomes or just one. Diploid means two complete sets (2n), with pairs of homologous chromosomes—one inherited from each parent. This is the usual state for body (somatic) cells, like human skin or muscle cells, which typically have 46 chromosomes arranged as 23 pairs. Gametes, on the other hand, carry only one set (haploid, n), so fertilization brings two sets back together. Geographical isolation is about how species become separate, not about chromosome counts. So the term for a cell with two sets of chromosomes is diploid cell.
