The ectoderm is additionally known as the outer layer that forms the pores and skin protecting of the animal and also its sense organs and nervous system.
The gastrula is the embryo stage that follows the blastula. It forms a shape having a hollow cup-shape that has three cell layers.

Overview of Gastrula
Gastrula is the early multicellular embryo that consists of germinal
layers from which the body's a number of organs are formed later.
The development of gastrula happens from the blastula that is a single-
layered hollow ball of cells. The structure of the blastula is formed becauseof the
repeated cleavage or cell division of the fertilized egg. Following the cleavage,
there is a duration of development where the motion of cells occurs. A
multicellular organism typically has a concentric arrangement of bodytissues. The
three sorts of embryonic cell layers additionally recognized as the germinal layers
that form these grownup tissues. The ectoderm is the outer layer, whereas the
mesoderm is the middle layer, and the endoderm is the innermost layer. In
the process ofgastrulation, the blastula cells reshuffle to form the three germinal
2. layers that later form various bodyorgan systems. In gastrulation, there is an
invagination or an inward motion of the blastula cells. Hence the spherical
embryo gets transformed to form the double-walled cup that is also recognized as
gastrula. The blastula's involuted phase that lines the double-walled
cup's interior forms the mesoderm and the endoderm, whereas the remaining cells
on the cup's exterior create the ectoderm. The ectoderm is additionally known as
the outer layer that forms the pores and skin overlaying of the animal
and also its sense organs and nervous system.
