Question

which best describes the processes of mitosis and meiosis?
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 and meiosis go through the pmat stages twice 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 once to produce diploid cells

Explanation:

• Mitosis is a single - cycle process (goes through PMAT stages once). The parent cell is diploid (\(2n\)), and the daughter cells produced are also diploid (\(2n\)). It is mainly for growth, repair, and asexual reproduction.
• Meiosis has two cycles (goes through PMAT stages twice). The starting cell is diploid (\(2n\)), and after meiosis I (reductional division) and meiosis II (equational division), the resulting cells are haploid (\(n\)). It is for sexual reproduction to produce gametes.

Answer:

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.
