Once a healthy biological male has reached adulthood, do his cells continue to divide by both mitosis and meiosis? Outline when each type of cell...

Somatic
cells (the cells that make up the body) divide constantly throughout a persons life, regardless
of whether they are male or femaleeven during adulthood, old cells die or are damaged, and new
cells are needed to replace them. In mitosis, a "parent" cell replicates itself, and
if all goes well, two new "daughter" cells are created that are identical to each
other and to the parent cell. Meiosis, however, serves the sole purpose of making gametes. In
the male reproductive system, this process is referred to more specifically as spermatogenesis,
and it occurs continuously throughout the person's life. Its important to realize that meiosis
only takes place inside the reproductive organs and that the end product is not two identical
cells but four haploid gametes.
