Vedclass · Answer

(C) In sea urchin development,the cleavage pattern is radial. During the fourth cleavage,the animal hemisphere cells divide meridionally to form eight cells called mesomeres. The vegetal hemisphere cells divide equatorially to form four macromeres and four micromeres. Mesomeres are destined to form the ectoderm of the embryo. Macromeres contribute to the endoderm and mesoderm,while micromeres give rise to the primary mesenchyme (mesoderm).

During the fourth and sixth cleavage of the zygote in sea urchin development,what is the fate of the resulting cells?
