Question

which example is considered a haploid cell?
a. two sets of chromosomes that are identical
b. a somatic cell with a complete set of paired chromosomes
c. the daughter cells that result from binary fission
d. a gamete or spore with one of each unpaired chromosome

Explanation:

A haploid cell contains a single, unpaired set of chromosomes (n), while diploid cells have two paired sets (2n).

• Option A describes a diploid cell (two chromosome sets).
• Option B: Somatic cells are diploid, with paired chromosomes.
• Option C: Binary fission produces cells identical to the parent; most parent cells here are diploid.
• Option D: Gametes (sex cells) and spores are haploid, carrying one unpaired copy of each chromosome.

Answer:

D. A gamete or spore with one of each unpaired chromosome
