A botanist is studying the phylogenetic relationships of plants using only their their morphological traits. Would specialized plants (like desert or rainforest plants) complicate this process, why or why not? Select all that apply. Select all that apply: a. Yes; they often appear similar but are not closely related to each other b. Yes; their traits are similar to plants across many environments c. No; their traits are shared by a common ancestor Od. Yes; they gained different traits than their close relatives because of their environment cross o cross c cross cross

DRAW IT Use the letters a–d to label where on the phylogenetictree each of the following derived characters appears.(A) flowers(B) embryos(C) seeds(D) vascular tissue
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.
Phylogenetic classification is based on _______. overall similarities habit of plants common evolutionary descendants all of these
2) All plant species are descended from a single common ancestor. In terms of phylogeny, together all plants (with their common ancestor) represent a a.Polyphyletic taxon b.Multiphyletic taxon c.Monophyletic taxon d.Paraphyletic taxon e.Uniphyletic taxon
Which of the following features is found in a rooted tree but not in an unrooted tree?a. Terminal nodesb. Internal nodesc. A common ancestor to all other nodesd. Branch lengths that represent the amount of evolutionary divergence between nodes
BIOMES & ADAPTIVE RADIATION Adaptive Radiation ven the type of biome these succulent plants are found in, identify 3 important stressors present in their environments. Now, describe how these pressures likely influenced the diversification of these plant lineages. Use one of the plant families listed above (and your representative species) to discuss as an example. (A well-developed paragraph is expected.)
Now you will practice identifying the phylogenetic tree that corresponds to a given character table. The following table shows three key events in the evolution of plants: the development of vascular tissue, the development of flowers, and the development of seeds. Plant groups Vascular Tissue Flowers Seeds Gymnosperms 1 0 1 Mosses 0 0 0 Ferns 1 0 0 Angiosperms 1 1 1 Select the phylogenetic tree that correctly represents the data in the character table.
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.
Despite changes in the approach for classifying plants (from artificial-, to natural-, to phylogenetic systems), what has been the common features or structure of these systems that can be attributed to the work- and influence of Linnaeus in the field of taxonomy?
Plants made the leap from water to land during the late Ordovician period (we think). In order to make it, various physical obstacles had to be overcome. Choose one adaptation and explore it further. What evidence do we have of this change? Are there specific fossils of plants that exhibit it? How do we think it may have developed? Not all of these changes occurred at the exact same time. Was your chosen adaptation one of the first or late to the game? including references are appreciated.
This figure identifies lineages as plants, non-vascular plants, vascular plants, seedless vascular plants, and seed plants. Which of these categories are paraphyletic and which are monophyletic?
While conducting a plant diversity survey in a temperate rainforest in Washington state, you come across a number of individuals of a low-lying plant species. These plants spread over the surface of moist groun and have numerous small stems that have tiny leaflets. They have root-like structures but do NOT have roots. Back at the lab, tests indicate that the majority of the plant material is haploid. The plant you discovered is likely most closely related to -a moss. -complex streptophyte algae. -a daisy -a conifer -a lycophyte
