A consortium of dairy and beef farmers has hired you to study the evolutionary origins of domestic cattle. They particularly want to know whether the humped zebu cattle of Asia and the cattle of Africa are derived from different species of wild cattle than European breeds. Outline a complete research program to study this question. Describe the sequence of steps you would need to do, what kind of data you would collect, and the methods you could use to evaluate possible trees and branches.
Why is Plant Taxonomy considered as the most basic and most derived/ synthetic field of Biology? Explain the significance and relevance of studying Plant Taxonomy.
Evaluate the following statements about seeds from two biology textbooks:
I. The seed coat is an adaptation that protects the plant embryo from damage, water loss, and infection.
II. Evolution has come up with a clever solution for protecting plant embryos: seed coats that prevent damage, water loss, and infection.
Do these statements accurately represent the evolution of seeds?
a) Yes, both statements are accurate.
b) No, neither statement is accurate.
c) Only the first statement is accurate.

- Review the life cycles of the three major plant groups (bryophyte or non-vascular plants, seedless vascular plants, and seed plants). Be able to identify the gametophyte and sporophyte generations in each plant group. Make one graph that shows patterns of changes in the following characteristics, as the different plant groups (bryophytes or non-vascular plants, seedless vascular plants, and seed plants) appeared or evolved on land through time. 1) size of the gametophyte generation 2) size of the sporophyte generation 3) biomass (amount of organic material) stored in the sporophyte 4) degree of dependence on water for fertilization Make sure the y- and x- axes of the graph, labels and title are included and correctly applied.arrow_forwardSummarize (very briefly) the evolutionary history of plants. You might just give the order in which they are thought to have evolved. What are the most recently evolved type of plants?arrow_forwardPhylogenetic 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.arrow_forward
- 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 lycophytearrow_forwardPhylogenetic analyses of land plants and their close relatives determined that the land plants form a monophyletic group (pass one-snip-test). This suggests, Select one: O a. There was a single transition from aquatic to terrestrial habitats b. Flowering plants arose first O c. No changes have occurred in lands plants since they transition to a terrestrial habitat O d. Wind-pollinated plants arose first e. There were many transitions from aquatic to terrestrial habitatsarrow_forwardLinnaeus is considered as father of taxonomy. Name two other botanists known for their contribution to the field of plant taxonomy?arrow_forward
- Draw your phylogenetic tree in the box below.arrow_forwardSome ancestral plants had a difficult transition to land, as challenges to survive caused plant evolution to develop very specialized adaptations over an extended amount of time. These are some of the challenges that plants faced: A. Avoiding desiccation B. Supporting larger bodies (against gravity) C Internally transporting substances D. Keeping gametes wet E. Keeping embryos wet For each of the above challenges. provide a structure/adaptation that plants have developed which mitigates that specific challenge. Must describe a structure or trait for all!arrow_forward(1) Seeds would be an example of an: I) autapomorphy II) plesiomorphy III) synapomorphy IV) symplesiomorphy (2) Flowers would be an example of an: I) autapomorphy II) plesiomorphy III) synapomorphy IV) symplesiomorphyarrow_forward
- What are trumpet cells in brown algae? What type of cells do they resemble in true plants? Is their presence in brown algae a sign that brown algae are related to the ancestors of true plants, or is it just a remarkable case of convergent evolution?arrow_forwardThere are two alternative hypotheses about the life cycle of the early vascular plants, the transformation hypothesis and the interpolation hypothesis. If Rhynia and Sciadophyton are the two generations of one species, which hypothesis would be favored? Briefly describe the other hypothesis.arrow_forwardNow 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.arrow_forward
