Steps of embryonic development Correct Answer-1) Zygote (fertilized egg) undergoes early cleavages -> morula (group of equivalent, undistinguishable cells) 2) As morula grows, cell acquires specific characteristics & some morphological differences (ex. embryonic axes) -> blastula (characterized by presence of hollow cavity, blastocele) 3) Gastrulation (gastrula) originates 3 definitive germ layers (ectoderm, mesoderm, endoderm) 4) Once scaffold & primordial for tissues & organs laid out...
