Study Objective Questions # 15 Cellular Mechanisms of Development 1. Describe the path of vertebrate development. Use appropriate diagrams. Begin as a zygote, which is a single fertilized egg. Undergoes cleavage when the cell divides rapidly into blastomeres until a solid ball of cells is produced. The cells are connected by tight junctions, the inner cells start to pump Na+ from their cytoplasm into the spaces between the cells, this form the blastula or blastocyst. Gastrulation occurs next and is when a sheet of cells contract on them and shove inward which creates the main axis of the vertebrate body with three germ layers. Next is the formation of the neural tube by neurulation. During cell migration, cells migrate to the distant tissues to become specified. Organogenesis and growth, now the cells just develop into its specific jobs. 2. Explain the different stages in insect development? Begins before fertilization, the action of maternal genes determines the
