WebLABORATORY #3 EARLY FROG DEVELOPMENT The stages to be examined are: unsegmented or zygote or uncleaved; early cleavage; late cleavage; blastula; early gastrula; late gastrula; neural groove. These may not all be in your slide box, so take only one slide at a time from the common supply. UNCLEAVED EGG: we need to see the … WebAfter the cleavage has produced over 100 cells, the embryo is called a blastula. The blastula is usually a spherical layer of cells (the blastoderm) surrounding a fluid-filled or yolk-filled cavity (the blastocoel). During cleavage, the zygote rapidly divides into multiple cells without increasing in size. Mammals at this stage form a structure ...

The characteristic features of the blastula stage are the presence of a well-defined cavity called the blastocoel. This is the beginning of the primary body cavity. The process of the formation of blastula is called blastulation.
