Create a hypothetical phylogenetic tree using 11 plant species listed below.  Chara, Nitella, Marchantia, Polytrichum, Equistem, Psilotum, Polypodium, Pinus, Zamia, Arabidopsis, and Lilium. Divide the species into five specific groups (Charophytes, Bryophytes, Monolithophytes, Gymnosperms, and Angiosperms) which will be the clades of your phylogenetic tree.

Recent DNA evidence suggests to some plant taxonomists that the traditional way of classifying flowering plants is not correct, and that flowering plants need to be completely reclassified. Other botanists disagree, saying it would be chaotic and unwise to disregard the historical classification groups. Argue for an against keeping traditional classification schemes.

A group composed of mosses, hornworts, club mosses, horsetails, ferns, gymnosperms and their common ancestor but not angiosperms is considered: Group of answer choices a. polyphyletic b. monophyletic c. paraphyletic

1. Of the plant groups included in Figure 1-1, which taxes have seeds? 2. Are the angiosperms more closely related to the bryophytes or the gymnosperms? 3. Explain your answer to question #2  4. Circle the node in Figure 1-1 that indicates the most recent common ancestor of gymnosperms and angiosperms.  5. List the characters that differentiate monocots and eudicots ( two groups of angiosperms) as seperate branches on the phylogenetic tree. In addition, give several examples of each.

Which of the following statements characterize the megaphyll line of evolution? A) They differ from microphylls by developing a single, unbranched vein rather than a branched vascular system.B) They are believed to have evolved from branching telomeres that flattened and developed photosynthetic tissue between the branches.C) They developed into leaves that can also be called lycophyllsD) They developed into the large leaves of the angiosperms

Make a DETAILED phlogenetic tree (Domain to Species) about the 4 main types of plants of plants: Mosses and Liverworts (Bryophytes) Ferns and Horsetails (Pteridophytes) Gymnosperms Angiosperms

What key traits distinguish each group from the other listed in the comparison? A) All land plants from green algae? B) Pteridophyta (ferns) from Bryophyta (mosses)? C) Angiosperms from ferns?

Match the following clades with the characteristics that they share   Clades: Bryophytes and Tracheophyta                                                                          Embryophyta and Charophycea                                                                    Chlorophyta and Streptophyta                                                                    Bryophytes and Tracheophyta   Characteristics: -Chlorophylls a and b are autotrophic -Alternation of generations -Rosettes in the plasma membrane  -Sporangia with walled spores

Which of the following statements best compares the two dominant lineages of modern angiosperms? -Monocots are monophyletic whereas eudicots have multiple origins. -Monocots have only one pistil per flower whereas eudicots have three. -Monocots have only one cotyledon whereas eudicots have two. -Monocots are lycophylls whereas eudicots are euphylls. -Monocots have only one stamen per flower whereas eudicots have six.
