Which statement best describes why a plant root tip is a good example of mitosis at work?

• A. Cells in the root tip undergo meiosis to produce haploid gametes that support sexual reproduction.
• B. Cells in the root apical meristem undergo mitosis to produce genetically identical daughter cells that enable root growth and repair.
• C. Cells in the root tip primarily increase root length by enlarging without cell division, so mitosis is not involved.
• D. Cells in the root tip undergo mitosis mainly to create genetic diversity by recombining homologous chromosomes.

Answer: (B)
