Which cell division is specifically for sex cells?

• A. Mitosis
• B. Meiosis
• C. Binary fission
• D. Budding

Answer: (B)

Meiosis is the division that makes sex cells. It involves two rounds of division that cut the chromosome number in half, producing haploid gametes like sperm and egg. This halving is essential so that when fertilization occurs, the offspring recover the normal diploid chromosome count. Meiosis also mixes genetic material, with crossing over during the first division and independent assortment of chromosomes, which increases variation among offspring.

In contrast, mitosis is the process used for growth and tissue maintenance, giving two genetically identical diploid daughter cells. Binary fission is how many bacteria reproduce asexually by splitting into two, without halving chromosome number. Budding is another form of asexual reproduction seen in some organisms, where a new individual grows off the parent. Because sex cells are produced specifically through division that halves the chromosome count and promotes genetic diversity, meiosis is the process responsible for making sex cells.
