Question

Quizplus · Accepted Answer

The inner cells of the zygote become the embryo. This is the beginning stage of embryonic development. The outer cells of the zygote form the placenta, which is responsible for providing nutrients and oxygen to the developing embryo. The embryo eventually attaches to the uterine wall as it continues to develop. While the heart will eventually form during the embryonic stage, it is not specifically formed from the inner cells of the zygote.
