Compare and contrast development during the period of the zygote with development during the embryonic period
What will be an ideal response?
The zygotic period occurs during the first two weeks following conception. It includes implantation of the zygote into the uterine wall, the development of the germinal disc that will eventually become the body, and the development of the placenta. The period of the embryo lasts from 3 to 8 weeks after conception. During this time, layers of tissue (e.g., ectoderm, mesoderm, endoderm) begin to shape the developing organism. This is also the time when all body structures and organs are formed.
