What is the primary difference between haploid and diploid cells in the context of meiosis?

• A. Haploid cells undergo mitosis, while diploid cells undergo meiosis.
• B. Haploid cells contain one set of chromosomes, while diploid cells contain two sets of chromosomes.
• C. Haploid cells are found in somatic tissues, while diploid cells are found in gametes.
• D. Haploid cells are produced during fertilization, while diploid cells are produced during meiosis.

Answer: (B)

Verified step by step guidance

1. Understand the definitions: Haploid cells have one complete set of chromosomes (n), while diploid cells have two complete sets of chromosomes (2n).
2. Recognize the context of meiosis: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of haploid cells from diploid cells.
3. Identify the role of haploid and diploid cells: Diploid cells are typically found in somatic tissues and undergo meiosis to produce haploid gametes (sperm and eggs).
4. Clarify the process: During meiosis, a diploid cell divides twice to produce four haploid cells, each with half the number of chromosomes as the original diploid cell.
5. Summarize the primary difference: The key distinction is that haploid cells contain one set of chromosomes, while diploid cells contain two sets, which is crucial for sexual reproduction and genetic diversity.
