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 4 (QUESTIONS AND ANSWERS) University of California, Davis BIS 2C 002C

homology - Answer- characters present in organisms because they were inherited from a common ancestor homoplasy - Answer- two structures with the same morphology, where this morphology was not inherited from a common ancestor (evolved multiple times independently) Conflict vs Congruence - Answer- whether or not new data correlates with the hypothesized phylogeny (congruence) or doesn't correlate with the hypothesized phylogeny (conflict) Cladograms - Answer- branch lengths are meaningl...

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.

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

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...
