Detailed explanation-1: -Final Answer: The correct sequence of embryonic development is: Zygote-Morula-Blastula-Gastrula-Embryo.
Detailed explanation-2: -The correct sequence in development is Fertilization → Zygote → Cleavage → Morula → Blastula → Gastrula.
Detailed explanation-3: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.
Detailed explanation-4: -The cleavage and blastula stage The initial growth stages of multi-cellular organisms start with a zygote cell, which then undergoes fast cell division to form the initial cell cluster, or ‘blastula’. This rapid division of cells is known as the process of ‘cleavage’.
Detailed explanation-5: -The Morula stage takes place before the formation of the blastula.
