Question 20 • Biology

Which best describes the processes of mitosis and meiosis?

Answer

Cells in mitosis go through the PMAT stages twice to produce diploid cells while cells in meiosis go through PMAT stages once to produce haploid cells.

Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells.

Cells in mitosis and meiosis go through the PMAT stages twice to produce haploid cells.

Cells in mitosis and meiosis go through the PMAT stages once to produce diploid cells.

Explanation

Mitosis has one round of cell division, passing through prophase, metaphase, anaphase, and telophase (PMAT) once. It produces daughter cells that retain the original diploid chromosome number. Meiosis has two rounds of division, so PMAT occurs twice, producing haploid cells with half the original chromosome number. Therefore, choice B correctly describes both processes.
