Define haploid cells

A haploid cell contains a single set of unpaired chromosomes, represented as \(n\). This is in contrast to diploid cells (\(2n\)), which contain paired homologous chromosomes.

Analyze the given options

• Option A: Daughter cells from binary fission are typically genetically identical to the parent prokaryotic cell, which does not represent the standard eukaryotic haploid/diploid alternation.
• Option B: A gamete (like sperm or egg) or a spore is the classic biological example of a haploid cell, containing exactly one of each unpaired chromosome.
• Option C: A somatic cell with paired chromosomes is diploid (\(2n\)).
• Option D: Two identical sets of chromosomes describe a diploid state.

Connect to cell division concepts

During Mitosis vs Meiosis, meiosis reduces the chromosome number by half to produce haploid gametes, ensuring that sexual reproduction restores the diploid number. Thus, Option B is the correct definition.
