Gastrulation Blastula (hollow ball of cells) transformed into the Gastrula (three-layered stage)
{"Image DocumentName": "Gastrulation Blastula (hollow ball of cells) transformed into the Gastrula (three-layered stage)", "Image ImageDescription": "Gastrula: structure made up of 2 layers of cells with an opening at one end. The point where the horse shoe almost touches is called the blastopore (small hole). In protostomes this will eventually form the mouth. In deuterostomes this will form the anus. Cells that are folding inward form a cavity lined with a 2nd layer of cells. Gastrulation - sorts all the cells into distinct cell layers (ectoderm, endoderm, and mesoderm)", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
