Question

Define gastrulation.

Answer 1

gastrulation is the process of embryonic development that changes the embryo from an brastula with single layer of a cell containing multiple layer of cell

Answer 2

Answer:

Gastrulation is a stage before the embryonic development in human beings. In this stage, a single membrane blastula is converted into the next phage, gastrula which is multilayered. Gastrula is divided into three different germ layers at the ending of this stage named Ectoderm (outer layer), Mesoderm (middle layer) and Endoderm (inner layer). This is found after the cleavage formation.
