Gastrula

Vedclass · Answer

(A) During embryonic development,the metabolic rate increases significantly as the complexity of the embryo grows. $1$. The $Gastrula$ stage involves extensive cell migration,morphogenetic movements,and the differentiation of the three germ layers ($Ectoderm$,$Mesoderm$,and $Endoderm$). $2$. These complex cellular activities require a high amount of energy,which is generated through aerobic respiration. $3$. Therefore,the $Gastrula$ stage is characterized by the highest rate of oxygen consumption compared to earlier stages like $Cleavage$,$Morula$,or $Blastula$.

In which of the following stages does the embryo consume the maximum amount of $O_2$?
