Answer:
Resulting structure of the experiment
The resulting structure of the experiment involving the development of 64-cell stage sea urchin by combining an isolated animal hemisphere with isolated micromeres is a recognizable pluteus larva.
Explanation
The animal hemisphere of the 64-cell stage sea urchin contains ectodermal, mesodermal, and endodermal cells, while the vegetal hemisphere contains only endodermal cells. Micromeres are small cells that arise from the vegetal pole and are involved in the formation of the skeleton and gut of the sea urchin.
When the animal hemisphere is combined with the micromeres, the micromeres induce the formation of the archenteron, which is the primitive gut of the sea urchin. The ectodermal cells of the animal hemisphere form the epidermis of the pluteus larva, while the mesodermal cells give rise to the coelomic cavities and muscles. The endodermal cells form the lining of the gut.
The resulting structure of this experiment is a recognizable pluteus larva because the combination of the animal hemisphere and micromeres has induced the formation of the archenteron and the differentiation of the ectodermal, mesodermal, and endodermal cells into the various tissues of the pluteus larva.
Conclusion
In conclusion, the combination of an isolated animal hemisphere with isolated micromeres in the development of a 64-cell stage sea urchin results in the formation of a recognizable pluteus larva. This experiment demonstrates the importance of cell interactions and induction in the development of complex organisms.
