PLEASE READ INSTRUCTIONS: If for any reason you cannot answer ALL THESE QUESTIONS, let someone else reply  :) thank you!! I will rate.


1) DRAW the Phylogenetic tree including ALL the following plant species:

 

  • Sphagnum (a bryophyte),
  • Lycopodium,
  • Isoetes,
  • Selaginella,
  • Polypodium,
  • Equisetum,
  • Psilotum,
  • Azolla.


2) Indicate on the phylogenic tree where the following traits evolved:

  • heterospory,
  • xylem,
  • microphylls,
  • megaphylls,
  • dichotomous branching,
  • highly reduced, scale-like megaphylls.



DETAILS: A "Phylogenetic tree" is a branching diagram or a tree showing the evolutionary relationships among various biological species. To reply to this question, you may know the evolutionary relationship between the plant species described above (Sphagnum (a bryophyte), Lycopodium, Isoetes, Selaginella, Polypodium, Equisetum, Psilotum, Azolla). I'm going to provide below an example of a Phylogenetic tree:

HERE is another example of how to construct a Phylogenetic tree:

You may choose any of the ways described above to construct the Phylogenetic tree, but REMEMBER, you're DRAWING this Phylogenetic tree with the organisms described above: (Sphagnum (a bryophyte), Lycopodium, Isoetes, Selaginella, Polypodium, Equisetum, Psilotum, Azolla), ALONG with indicating where these evolutionary traits took place (heterospory, xylem, microphylls, megaphylls, dichotomous branching, highly reduced, scale-like megaphylls).


Please let me know if you have further questions. THANK YOU! :-)
