Platyhelminthes has the greatest complexity, and it is more closely related to Nematoda than to Cnidaria. B. Nematoda has the greatest complexity, and it is more closely related to Platyhelminthes than to Cnidaria. C. Cnidaria has the greatest complexity, and it is more closely related to Platyhelminthes than to Nematoda. D. The complexity is equal among all three groups, but Platyhelminthes is more closely related to Cnidaria than to Nematoda.
Which of the following combinations of phylum anddescription is incorrect?(A) Echinodermata—bilateral symmetry as a larva, coelomate(B) Nematoda—roundworms, pseudocoelomate(C) Platyhelminthes—flatworms, gastrovascular cavity,acoelomate(D) Porifera—gastrovascular cavity, coelomate
Make a bracketed or indented dichotomous key for identifying and classifying the 9 major Invertebrate Phyla: Porifera Cnidaria Ctenophora Platyhelminthes Nematoda Mollusca Annelida Arthropoda Echinodermata Rules to follow in constructing a dichotomous key: Only use observable characteristics Start with major characteristics, placing organisms into two groups at each stage Use a single characteristic at a time Use contrasting characteristics at each stage i.e. 1(a) short, 1(b) tall Avoid using the same characteristics
Using the examples from the animals you have studied in this lab, give the differences between the following phyla: Echinodermata and planaria Cnidaria and Porifera Annelida and Nematoda Cnidaria and Mollusca Echinodermata and Chordata 2. Charles a Biology student in California has found at the beach an animal he cannot name. What are some of the questions that he should ask to help determine the phylum of the animal? Based on the data that you recorded during this lab do you see a relationship between symmetry, cephalization, and number of germ layers? Can you tell what germ layer appears last? Name three characteristics or features in the phyla studied that you could tell are ancestral or primitive and three that you may call advance? Explain further?
An organism classified in phylum Mollusca that is a predator with tentacles, a brain and complex eyes would be classified into which group? gastropod cephalopod bivalve none of the above Which structure from the list below is made up of specialized cells called cnidocytes? Tentacle Bud mesoglea epidermis (ectoderm) Teste (spermerary) Reproductive polyp Foot Ovary Feeding polyp Gastrovascular cavity Mouth hydrostatic skeleton medusa
For context: This activity will examine the classification of invertebrates and the methods used to determine relationships among the many invertebrate phyla. Question: Are there newer trends in determining evolutionary relationships? If yes, what are they?
