You say you are studying Cellular Biology in Illinois?
You might want to review some of your high school classes on the subject before your embarass yourself any further.
The study of the development of the ZYGOTE is called EMBRYOLOGY. The zygote gets its instructions for its growth from the DNA that it inherits from its parents. Zygotes are living organisms and, therefore, must obtain oxygen and food and eliminate wastes. The manner in which the zygote reads the instructions from the DNA is not understood, though EMBRYONIC INDUCTION, a phenomenon in which tissues influence the differentiation of adjoining cells, has been demonstrated in many species.
