Question

A researcher obtains two frog embryos at the gastrula stage of development. She carefully removes a cluster of cells from a location that she knows whould normally become neural tube tissue and transplants it into the second gastrula in a location that would normally become skin. Does the second gastula develop two neural tubes? Explain your answer.

Answer 1

no, it dos not.

Step-by-step explanation:

Gastrulation is the stage when the blastula folds in on itself and enlarges. It is the earliest stage of embryo development and it is the beginning of a multilayered structure. Later three layers of cells are formed, the meso-derm, ecto-derm and the endo-derm. The Meso-derm develops into organs, while the Ecto-derm forms the skin and the endo-derm forms the inner linings of organs. If cells were removed from one gastrulated frog to another, depending on the layer it was placed it, this would be the type of body tissue it would become. Theoretically, it should not form aberrant tissue but it should correct itself or abort fetal formation.
