Phylogenetic trees are used to show the evolutionary relationships among various biological species and are usually based upon shared derived characters. In constructing phylogenetic trees, it is useful to first draw up a character table to show the presence or absence of characters among the various groups of organisms being studied.
a. Draw up a character table based upon the following shared derived characters of land plants: flowers, seeds, vascular tissues, and dependent embryos. Your character table must include the names/descriptions of the plant groups that are being characterized.
b. Construct a phylogenetic tree based on this data.
Constructing a Phylogenetic Tree
Now, you are going to create and the interpret your own phylogenetic tree. Take a look at the characteristics for these organisms.
Plant Group
Photosynthesis?
Seeds?
Water-conducting Tissue?
Flowers?
Ferns
X
Gymnosperms
Mosses
Angiosperms
Using the characteristics from the table above, determine where each of these organisms belongs on the tree below, then answer the questions.
A
В
What characteristic appears just before group C branches off (the starred location)?
flowers
water conducting tissue
seeds
O photosynthesis

- Explain why plants being polyploid makes using the phylogenetic species concept difficult to use. Be sure to explain how the phylogenetic species concept attempts to classify organisms into distinct species. How can scientists still use the phylogenetic species concept to classify land plants, despite the majority being polyploid?
