This is the correct option since epiboly is movement of cells which occurs in early embryos at the same time as gastrulation whereas emboly is formation of gastrula from blastula by invagination of germ layers.

WebApr 6, 2024 · In frogs, these layers are formed by the processes of epiboly, emboly and invagination. 2)The epibody consists of the epibolic movement is the way in which a layer of epithelial cells spread. This can be achieved in multiple ways. 3)The embryo is converted into a double-walled, cup-shaped structure. The new internal wall lines the archenteron ... WebInvagination - an emboly movement. Morphogenetic movement in gastrulation stage is generally described in two terms – Epiboly and emboly. Emboly means the folding inside or insertion of the cell sheet into the embryo. Epiboly means expansion or spreading of the cell sheet over other cells. Both these movements are opposite in nature, but help ...

Epiboly represents the spreading of embryonic cells over a vegetal yolk mass, resulting in ectoderm to cover the embryo. Emboly (ingression, involution, invagination) relocates the mesendodermal anlagen into the inner embryo. Convergence of vegetal and lateral cells to the dorsal axis and extension establish the long axis of the embryo.
