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? the tree depicts uncertainty about whether the bryophytes or the vascular plants evolved first the tree depicts an evolutionary hypothesis the tree indicates that seeds are a shared ancestral character of all vascular plants the tree includes evolution of convergent characteristics

However, generally speaking, a phylogenetic tree would depict an evolutionary hypothesis (option b), showing the relationships between different species or groups based on their evolutionary history. It would not typically depict uncertainty about the order of Show more…

Nonvascular plants (bryophytes), Seedless vascular plants, Gymnosperms, Angiosperms. 40) Based upon the figure above, the phylogenetic tree: 1. depicts uncertainty about whether the bryophytes or the vascular plants evolved first. 2. depicts an evolutionary hypothesis. 3. includes polytomies. 4. shows that members of the phylum Pterophyta are the closest living relatives to the seed plants. 5. indicates that seeds are a shared ancestral character of all vascular plants. A) 1 and 2 B) 2 and 3 C) 1, 2, and 3 D) 1, 2, and 4.

Match the major characteristics with phyla or class of plants. These non-vascular, seedless plants have a dominant and photosynthetic gametophyte/haploid life cycle. These vascular yet seedless plants have sporangia that form the visible reproductive structure known as the sorus. These vascular plants produce seeds from reproductive structures known as cones. These vascular plants produce seeds with double fertilization which creates an embryo and endosperm. This class on angiosperms has a single embryonic leaf and pollen grains with one opening. This class on angiosperms has two embryonic leaves and pollen grains with three openings. A. Bryophyta (mosses) B. Monocots C. Eudictos D. Anthophyta E. Monilophyta (ferns) F. Coniferophtya

Gymnosperms and angiosperms both produce flowers. c. Gymnosperms and angiosperms both produce tracheids, but not vessels, in their vascular tissues. d. Gymnosperms and angiosperms both produce fruits. e. none of the above
