Across
  1. 2. the leaf-like portion of the thallus
  2. 5. gelatinous chemicals produced by seaweeds that are used in food processing
  3. 7. an important phycocolloid that is used extensively as a stabilizer in the manufacture of dairy products
  4. 8. contains sperm; is carried by water currents
  5. 10. the farming of seaweed
  6. 13. the name for the complete body of seaweed
  7. 14. a phycocolloid that is used for its ability to form jellies
  8. 17. a diploid that results from the fusion of gametes
  9. 19. an example of this is a life history with two generations
  10. 20. a shape that coralline algae take; it covers rocks
  11. 21. through meiosis this diploid produces haploid cells
  12. 22. spores that have flagella for movement
  13. 23. process by which seaweeds produce haploid spores of gametes
  14. 24. diploid spores produced by the carposporophyte
  15. 27. also called flowering plants; they are the dominant plants on land
  16. 28. land plants that are tolerant of salt
  17. 29. a phycocolloid that is used to give body to dairy products
  18. 30. a haploid that produces haploid gametes
  19. 33. plants adapted to live along tropical and subtropical shores
  20. 34. stem-like structure of the seaweed
  21. 35. most complex and largest of all brown algaes
  22. 36. the common name for macrophytes and macroalgae
Down
  1. 1. red algae that deposit calcium carbonate within their cell walls
  2. 3. among the richest, most productive environments in the marine realm; also called forests
  3. 4. gas-filled bladders that keep the blades close to the surface
  4. 6. an area in the Atlantic that gets its name from a certain type of weed
  5. 9. when cells of seaweed divide and produce identical cells
  6. 11. red pigment in red algae; masks chlorophyll
  7. 12. fusing between two of these ensures that the new generation has genetic information from both parents
  8. 15. organisms that are capable of using light energy to preform photosynthesis
  9. 16. causes the olive green/dark brown color of brown algae
  10. 18. consists of many segments with deposits of calcium carbonate
  11. 25. gas-filled floats found in many species of brown algae; also known as wracks
  12. 26. plants that have adapted to life in the marine environment; despite their name, they are not grasses
  13. 31. the name for salt-tolerant plants
  14. 32. structure that looks like roots and anchors the thallus to the bottom
