Across
  1. 1. middle layer of the gastrula (i.e. notochord, skeletal muscle, kidney tubules, red blood cells)
  2. 3. complete split of the blastula/blastocysts
  3. 5. series of changes in the state of the cell, tissue, organ, or organism
  4. 6. cell that can differentiate into all cell types in a body (not the first cells of an organism)
  5. 8. second stage of embryonic development
  6. 10. first stage of embryonic development
  7. 14. outer layer of the gastrula (i.e. epidermis, brain, neurons)
  8. 16. cell that can differentiate into some cell types in a body
  9. 18. cell that can only differentiate into one cell type in a body
Down
  1. 2. inner layer of the gastrula (i.e. pancreatic acinar cells, thyroid follicular cells, lung alveolar cells)
  2. 4. incomplete split of the blastoderm
  3. 7. fifth stage of embryonic development
  4. 9. third stage of embryonic development
  5. 11. gets bigger with age without a limit on size
  6. 12. size gets bigger with age, but reach a certain size where you won’t get bigger
  7. 13. fourth stage of embryonic development
  8. 15. increase in weight or size
  9. 17. cell that can differentiate into all cell types in a body (the first cells of an organism)
