Question

Gastrulation produces an oval,three-layered sheet known as the
A)chorion.
B)blastula.
C)embryonic disc.
D)morula.
E)blastocyst.

Accepted Answer

Gastrulation produces the embryonic disc, which is an oval, three-layered sheet. The other options are incorrect as they refer to different stages of embryonic development. The blastula is the stage before gastrulation where the embryo is a hollow ball of cells, the morula is an earlier stage where the embryo is a solid ball of cells, and the blastocyst is a later stage where the embryo has formed a fluid-filled cavity. The chorion is a membrane that develops later and is not a product of gastrulation.
