Describe the stages of animal development from fertilization through the gastrula.
fertilization, cleavage, blastulation, and gastrulation. Fertilization unites sperm and egg to form a zygote, which then undergoes cleavage, a series of cell divisions that increase cell number but not size. This leads to the formation of a morula, a solid ball of cells, which then develops into a blastula, a hollow ball of cells. Finally, gastrulation involves the rearrangement of cells in the blastula to form the three primary germ layers: ectoderm, mesoderm, and endoderm, resulting in the formation of the gastrula.
