Verified
During the germinal period,the first task of the zygote's outer cells is:
A) differentiation.
B) duplication.
C) germination.
D) implantation.
Germinal Period
The initial two weeks of prenatal development after conception, characterized by rapid cell division and the attachment of the zygote to the uterine wall.
Zygote's Outer Cells
The cells on the periphery of a zygote (the earliest embryonic stage) that contribute to the development of the placenta and other supporting structures for the embryo.
Implantation
The process, beginning about 10 days after conception, in which the developing organism burrows into the uterus, where it can be nourished and protected as it continues to develop.
- Elucidate on the sequence of events and the effects concerning implantation in the prenatal period and the development of the placenta.

Final Answer :
D
Explanation :
During the germinal period, the first task of the zygote's outer cells is to implant themselves in the uterine wall, which is known as implantation. Choice A (differentiation) occurs later in the embryonic period, as cells begin to specialize and take on specific functions. Choice B (duplication) and Choice C (germination) are not accurate descriptions of the initial task of the zygote's outer cells during the germinal period.
