Pre-Lab 7: Introduction to Metazoa (Score: Question 1. Study the phylogeny of animals in figure 7.3. Where are humans on this phylogeny? What are the defining features of the phylum to which humans belong? Humans are on the chordata. The defining features are notochord, dorsal hollow nerve chord, and post-anal tail. Question 2. Study the phylogeny of animals in figure 7.3. What feature of the phylogeny supports the fact that deep relationships among animals remain unresolved? Polytomy:sho...

Question 1. What two things do nodes represent on phylogenies? Nodes represent the most recent common ancestor of two or more descendant lineages and represent a speciation event. Question 2. Compare the branching patterns of phylogenies 1-3 above. Which statement below correctly describes the patterns among trees 1-3? Tree 1 = Tree 2 Question 3. Which node represents the MRCA for taxa F and G? 3 Question 4. Which taxon or taxa is/are the sister group to E + F? D, G, H Question 5. If y...

Pre-lab 5: Introduction to Plant Diversity II Question 1. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage does pollen provide to seed plants in terms of their reproductive biology? Pollen is advantageous because it does not need water for the male cell to reach the female cell. Instead, pollinators transfer the different cells. Question 2. In contrast to Bryophytes, Lycophytes, and Monilophytes what specific advantage do seeds provide to seed plants in terms...

Pre-lab 6: Botanical Conservatory and Fungal Diversity (Score: 4.75/5) Question 1. Identify two reasons why maintaining a large, living plant collection is an important public and scientific resource. It lets us study different types of plants without having to travel all over the world and it teaches us better methods of conservation. Question 2. In figure 6.2 above, which season (X or Y) would correspond to winter at point A? Season X Question 3. On which side (left or right) of figure...

Pre-lab 4: Introduction to Plant Diversity I #1 Based on the figure is it correct to state that we understand deep relationships about Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees No because there is no first node, just several species that branch out as possible base taxa. The ambiguity is represented through the polytomy. #2 Do a little internet research and provide t

Most often, eukaryotes call to mind large and conspicuous animals and plants, but there are many eukaryotes that are not visible to the naked eye. Recall from lab 2 that the word ‘microbe’ is used to refer to microscopic organisms in any of the domains and viruses. In lab 3, you will be introduced to microbial eukaryotes, a group that includes several disparate lineages with diverse ecology and life history. The occur in most habitats worldwide, are key players in symbiotic interactions,...
