Arrange the processes in the order they occur during embryonic development and cell differentiation.

The process in order they occur during embryonic development are:

Cleavage or blastulation ,Implantation,Gastrulation.

Explanation:

After the fertilization the zygote is form.The first step of embryonic development involves the cleavage of the zygote that leads to the formation of a hollow multicellular developmental stage called Blastula.Next to Blastulation occurs implantation of the blastocyst  on the endometrial wall of the uterus.The final process is Gastrulation , during which the blastocystchanges into gastrular larva with three primary germ layers Namely, Ectoderm, endoderm and mesoderm. Which give rise to differnt organs.
