Answer: The zygote phase is followed by an embryo. However both the stages present a few notable differences:
Zygote | Embryo |
Zygote is unicellular. | The embryo stage involves the formation of organs and thus the embryo is multicellular. |
The method of generation of the zygote is termed fertilization. | Embryogenesis is the scientific term used to describe the formation of the embryo. |
In medical terms, we refer zygote as zygocyte. | Medical students refer embryo as a diploid eukaryote. |
