1. Bryophytes Making the transition from water to land

2. Adapting to life on land… Some structures to prevent water lossSome structures to prevent water loss Thin bodies absorb waterThin bodies absorb water Short bodies (transport water cell to cell)Short bodies (transport water cell to cell) Leaf and root like structuresLeaf and root like structures

3. Algae and Plants share… Chloroplast & get energy from the sunChloroplast & get energy from the sun Cell-wall material (cellulose)Cell-wall material (cellulose) Energy storage molecule (starch)Energy storage molecule (starch) Eukaryotic & multi-cellularEukaryotic & multi-cellular

4. Besides those traits, all plants… Have alternation of generationsHave alternation of generations –Haploid fuse sex cells to become diploid –Diploid undergo meiosis to become haploid Haploid and diploid generations have very different shapesHaploid and diploid generations have very different shapes

5. Bryophyte: Pseudo Roots (Liverwort)

6. Bryophyte: Pseudo Roots

8. Bryophyte: Pseudo Leaves

10. Bryophyte: Stomata (pores)

11. Bryophyte: Cuticles

12. Gametophyte (main plant body, “leaves”), haploid Rhizoids, haploid Bryophyte Anatomy

13. Gametophyte makes gametes (sperm and eggs), haploid Sperm have tails to swim in the moisture on the plant to another nearby plant in order to fertilize the egg. Bryophyte Anatomy

14. Sperm Sperm being released Eggs for sperm to fertilize

15. Fertilized eggs (diploid) grow into a sporophyte The sporophyte (diploid) grows up from the top of the gametophyte (haploid) Bryophyte Anatomy

16. The sporophyte (diploid) is made up of a stalk and capsule… The sporophyte (diploid) goes through meiosis and released spores (haploid) from the capsule.

17. Bryophyte Anatomy The spore (haploid) grows into a gametophyte (haploid)

18. Bryophyte Anatomy Gametophyte (Haploid) Sporophyte (Diploid) Rhizoid Gametophyte (body with “leaves”) Stalk (Seta) Capsule

19. Bryophyte Life Cycle

20. Bryophyte: Moss Species

24. Bryophyte: Liverwort Species

27. Bryophyte: Hornwort Species

30. Bryophyte: Native Species (Dead! No winter rains!)

31. Bryophyte: Native Species (Dead and not quite dead!)

32. Bryophyte: Native Species (Still alive!)

33. Bryophyte: Native Species (After pouring water on it…) Blurry footage of moss reviving: Part 1 Blurry footage of moss reviving: Part 2

35. I’m so happy it’s alive!

36. Mushroom growing with liverworts and mosses. Super cute!
