Document Summary

Developmental biology from cellular level to an organ. Offers the best model of embryo developmental history of leopard frog: fertilization-oocyte, cleavage phase- dividing cellular matter into smaller cells (blastula, gastrulation phase- generate endonderm, mesoderm, and ectoderm, organogenesis- organ synthesis, larval stage, maturity. Dividing cells of fertilized egg from 3 distinct embryonic germ laters. Gastrula gives rise to to ectoderm, mesoderm, endoderm, and germ layers. Fate maps: demonstrates early gastrula stage, which demonstrates germ layers already.

Another way is to attach a radio-level or an inert die. Cytoplasm of on cell is yellower than the other, then these yellow cell divides into smaller cells and contributed to stomach cells later. You can physically remove the yellow cell and determine if this cell is dependent to other cells.
