Which of the following correctly describes gastrulation in frog embryos?
A) causes the ectoderm and endoderm layers to invert
B) occurs along the primitive streak in the animal hemisphere
C) proceeds by involution as cells roll over the lip of the blastopore
D) occurs within the inner cell mass that is embedded in the large amount of yolk

Question

Quizplus · Accepted Answer

Gastrulation in frog embryos involves the process of involution, where cells move inward over the lip of the blastopore, leading to the formation of the germ layers. This is a key process in the development of the embryo, allowing for the differentiation of cells into the ectoderm, mesoderm, and endoderm.
