Chapter 24, Problem 39A

Summary Introduction

To write:

The growth of the new tissue, when the portions of the embryo responsible for the tail development, were transferred to fluid in the gastrula.

Introduction:

During the gastrulation phase, due to the movements of cell, a huge embryo reorganization from a round ball of cells known as The Blastula which transforms to a multi-layered organism.

Explanation of Solution

• The new tissue grew on the lower end i.e there will a formation of duplicate tail which which then forms a second newt.

• Transplanting of tissue must have taken place in the second newt, and builds their structure from a group of cells those are transplanted.
• To form a second newt the transplanted tissues must have checked with the layers of the surrounding recipient tissue.

Conclusion

Thus, Gastrulation is the early embryonic development of most animals where the cells gets reorganised into a multilayered structure known as gastrula
