Across
  1. 3. the study of embryos
  2. 4. vascular plants that have naked seeds and needle like leaves
  3. 7. organisms that are unicellular and live in extreme environments
  4. 12. domain that has unicellular and multicellular organisms, the one YOU belong to
  5. 13. preserved remains or traces of organisms that once lived
  6. 15. vascular plants that have fruits and flowers
  7. 19. structures that are similar anatomical features from different species that share common evolutionary origin (ex- similar arm structure between humans, bats, dogs)
  8. 20. animal phyla that have stinging cells
  9. 21. two name naming system
  10. 23. the most simple plant phyla
  11. 25. the law that states that the fossils deeper in the ground are older and more simple than the ones closer to the surface
  12. 26. kingdom that has both unicellular and multicellular organisms that are heterotrophs by absorbing nutrients (ex- mushrooms)
  13. 27. kingdom that has multicellular autotrophs (ex- oak tree)
  14. 28. animal phyla that has a spinal cord, the one you belong to
Down
  1. 1. physical or behavioral changes in an organism over time
  2. 2. structures that once served a function for the organism, but no longer serve a purpose for the organism (ex- whale pelvis)
  3. 5. the natural process by which living things with the traits best suited for the environment survive and reproduce
  4. 6. man known as the father of evolution
  5. 8. kingdom that has multicellular heterotrophs (ex- you)
  6. 9. islands that are the birthplace of evolution
  7. 10. most simple phylum of animals that are porous
  8. 11. structures that are found in different species that perform the same function, but do not come from the same evolutionary origin (birds and butterflies having wings)
  9. 14. animal phyla that has many jointed/segmented legs
  10. 16. kingdoms that has both unicellular and multicellular organisms that can be animal-like, plant-like, and fungi-like
  11. 17. animal phyla that has soft bodies and true shells
  12. 18. largest domain that has all unicellular organisms
  13. 22. animal phyla that has spiny skin
  14. 24. change in DNA
  15. 26. simple, vascular plants that have special leaves called fronds
