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,...

Postlab 2: Introduction to Bacterial and Archaeal Diversity Directions: Complete the questions below by the start time of your next lab. Be precise in your answers and pay attention to your reasoning. Your postlab is worth 5 points total. 1. (1 pts) Fill in the concept map below with the following terms related to microbe metabolism: chemo- , hetero-, chemical, organic, photo-, light, inorganic, auto-, litho-, organo-. Some terms may be used more than once. 2a. (0.25 pts) How many differen...

Bis 2C, Pre-Lab #2 Bacteria and Archaea are often collectively referred to as prokaryotes because they lack a nucleus (pro=before, karyon=nucleus). But, as you can see from figure 2.1, they are not each other’s closest relatives. Because bacteria and archaea are so diverse, they can be difficult to characterize. However, when compared to eukaryotes, they have significant differences in their general biology including, reproduction, organization of genetic material, and a lack of membrane...

Question 1. Based on figure 4.1, is it correct to state that we understand deep relationships among Eukaryotes? How do we represent ambiguity in branching pattern on phylogenetic trees? Hint: look at figure 1.27. No, we cannot say we understand deep relationships among Eukaryotes because there is a polytomy that represents ambiguity on the phylogenetic tree. No, you cannot define deep relationships amongst eukaryotes because the nodes include polytomies which signifies ambiguity/indefinite...

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 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...

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...
