It is a form of blastula that develops from a berrylike cluster of cells, the morula. A cavity appears in the morula between the cells of the inner cell mass and the enveloping layer. This cavity becomes filled with fluid. The blastocyst differs from the blastula in that it is composed of two already differentiated …
WebThe inner sphere, or germ layer, is called the endoderm, and the outer germ layer is called the ectoderm. Gastrulation is when the first hollow ball of cells formed during development folds in to form a second sphere. The outer sphere is the ectoderm and the inner sphere is the mesoderm.

By the fifth or sixth day, the fertilized egg is known as a blastocyst — a rapidly dividing ball of cells. The inner group of cells will become the embryo. The outer group will become the cells that nourish and protect it. WebSep 7, 2024 · Some 15 hours later, the two cells divide to become four. And at the end of 3 days, the fertilized egg cell has become a berry-like structure made up of 16 cells. This structure is called a morula, which is Latin for mulberry.
