Question

A 4d blastomere forms in which type of coelomates?

Answer 1

In Schizocoelomates the Zygote exhibits spiral cleavage. Embryonic mesoderm is formed through Teloblastic method. In this method a single micromere called 4d blastomere or mesentoblast cell present at the rim of blastomere or mesentoblast cell present at the rim of blastopore proliferates to form meoderm between the developing archenterm( endoderm) and the body wall ( ectoderm), in the blastocoel.
