Explanation:
Detailed explanation-1: -Final Answer: The correct sequence of embryonic development is: Zygote-Morula-Blastula-Gastrula-Embryo.
Detailed explanation-2: -The process divides into five stages: embryonic, pseudoglandular, canalicular, saccular, and alveolar stage. Although the process begins early on in fetal development, complete maturation does not take place until the child is approximately 8 years of age.
Detailed explanation-3: -Morula. The morula is observed on day 4 and is formed after the compaction and fusion of blastomeres of the dividing embryos. As the morula continues to develop, fluid starts to accumulate forming a cavity, the blastocoel, giving rise to the blastocyst.
