2. Draw a phylogenetic tree that distinguishes between bryophytes, lycophytes, pteridophytes, gymnosperms, and angiosperms. Indicate the following traits on your phylogeny: stomata, vessel elements, roots, tracheids, true leaves, wood, seeds, pollen, and flowers. For each of these traits indicate which tissue system they belong to and what meristem they're derived from.

Construct a cladogram based on the following data. Mosses are plants with no vascular tissue. Horsetails, ferns, gymnosperms (pines and other plants with naked seeds), and angiosperms (flowering plants) are all vascular plants. Seeds are absent in all but the gymnosperms and angiosperms. Angiosperms are the only seed plants with flowers. (Hint: To help you construct the cladogram, draw a simple table showing which characters are present in each group.)

Construct a cladogram based on the following data. Mosses are plants with no vascular tissue. Horsetails, ferns, gymnosperms (pines and other plants with naked seeds), and angiosperms (flowering plants) are all vascular plants. Seeds are absent in all but the gymnosperms and angiosperms. Angiosperms are the only seed plants with flowers. (Hint: To help you construct the cladogram, draw a simple table showing which characters are present in each group. See Fig. $23-9 .$ )
Use the figure to answer the following question: Gymnosperms and angiosperms are both types of plants that produce seeds. Nonvascular plants (bryophytes) Seedless vascular plants Gymnosperms Angiosperms Which of the following claims is best supported by this phylogenetic tree? a) The tree depicts uncertainty about whether the bryophytes or the vascular plants evolved first. b) The tree depicts an evolutionary hypothesis. c) The tree indicates that seeds are a shared ancestral character of all vascular plants. d) The tree includes the evolution of convergent characteristics.
