Question
Chapter 11, Problem 1AAATB
Summary Introduction
To write:
An evolutionary tree among the flowering trees listed according to the Linnaeus classification.
Introduction:
Linnaeus classification assigns each organism a kingdom, phylum, class, order, family, genus and species. Each level is included in the level above it and levels get increasingly specific from kingdom to species. This classification is not based on evolution. The phylogenetic classification names the group of organisms that have descended from a common ancestor.

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.

Select the phylogenetic tree that correctly represents the data in the character table.
Linnaeus is considered as father of taxonomy. Name two other botanists known for their contribution to the field of plant taxonomy?
A taxonomist discovers a plant species that is unknown to science. Using your knowledge of the science of taxonomy gained through this course, discuss in a short essay how this taxonomist can go about describing the new species, and what would be important to do during this process.
You need to mention: Resources where he/she/they can study the plant and other plant collections, species concepts, taxonomic evidence that can be used and how these can be analysed, type specimens and also nomenclature (what is necessary for him/her/them to publish the name).

- Create a hypothetical phylogenetic tree using 11 plant species listed below. Chara, Nitella, Marchantia, Polytrichum, Equistem, Psilotum, Polypodium, Pinus, Zamia, Arabidopsis, and Lilium. Divide the species into five specific groups (Charophytes, Bryophytes, Monolithophytes, Gymnosperms, and Angiosperms) which will be the clades of your phylogenetic tree.arrow_forwardConstruct 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 vascularplants. Seeds are absent in all but the gymnosperms and angiosperms. Angiosperms are the only seed plants with flowersarrow_forwardDespite 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?arrow_forward
- 1) For each of the organisms in the following table, complete the empty columns with an appropriate answer for each taxa. Organism Gymnosperm Angiosperm Sister Taxa Derived Trait Ancestral Trait Mode of Reproductionarrow_forwardYou are asked to survey an area and identify all plant and animal species you come across. On your survey, you come across a plant you are not familiar with and must do some research to figure out what it is. To do this, your first step is to determine whether this plant is classified in the class Monocotyledonae or a Eudicotyledonae. Explain how you can tell if this plant is a Monocot or Eudicot by describing the differences in their flowers, seeds, roots, stems, and leaves. 1.arrow_forwardExamine the table of characters given for four different species of flower.

Take a look at the characteristics for these organisms. Plant Group Photosynthesis? Seeds? Water-conducting Tissue? Flowers?

- Draw a tree depicting our current understanding of land plant phylogeny. Include the four major groups of land plants at the tips of your tree, label the common ancestor of land plants, and mark where each of the critical innovations arose: embryo, sporopollenin, vascular tissue, seeds, flowers.arrow_forwardList FOUR examples of angiosperm and/or gymnosperm plant species that are economically important. A species could have more than one use (for example, species "x" is an angiosperm and its tuber is used as food, for drink and at the same time it is medicinal). PUT A PHOTO OF EACH ONE, identify with common (or scientific) name.arrow_forwardCompare and contrast the alternation of generations in pines and angiosperms. This must be very detailed and include all major structures and process involves. Be sure to include when the plants are haploid or diploid. You can use a list as long as order is clear. Be sure to clearly write out structure and processes and indicate which things are the same and which are different.arrow_forward
