Quizplus · Accepted Answer

The period of time from conception to implantation is referred to as the period of the zygote because during this time, the single-celled zygote begins to divide and form a cluster of cells that will eventually implant into the uterine wall. This period typically lasts about 10-14 days after fertilization. The embryonic period begins after implantation and lasts until the end of the 8th week of gestation. The fetal period begins at week 9 and lasts until birth. The period of cellular replication is a broader term that refers to the period of prenatal development during which cells rapidly divide and specialize to form different tissues and organs.
