In the experiment by Spemann and Mangold (which was conducted using an amphibian in
1924), not only did a second notochord form from the transplanted cells, but cells surrounding
the transplanted cells also became part of the second notochord. What does thisfinding suggest
about the process of animal (or amphibian) development?
a. All cells in an embryo have a defined fate that cannot be changed.
b. Having two notochords may be adaptive
c. Embryo transplantation experiments are difficult and usually end in failure
d. Certain embryonic cells have the ability to induce the differentiation of neighboring cells
e. The nervous system controls organogenesis during early embryo development anddisruption
of this system will lead to abnormalities during development
Ans: D. Certain embryonic cells have the ability to induce the differentiation of neighboring
cells
