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