Question

Gastrulation of frog is completed in ......days​

Answer 1

≈≈> As gastrulation continues, the cells pushing inward become the mesoderm and endoderm layers. The cells that cover the outside of the blastula end up becoming the ectoderm. By the end of gastrulation in frogs, we've got the gastrula, or three-layered embryo made up of the endoderm, mesoderm, and ectoderm.

Answer 2

As in the process of gastrulation the cells comes inward and are called mesoderm and also the endoderm layer . The cells that cover the blastula from outside they are called ectoderm . When the gastrulation process comes to an end and then we get the blastula with three layered embryo which is made up of mesoderm, endoderm and ectoderm
