Question
Chapter 23, Problem 10TYU
Summary Introduction
To determine: Some of the criteria and tools that biologists might use to assign the different types of protists to monophyletic groups.
Introduction: Previous classification considers three different types of taxonomic relationships that are shown in a cladogram. These different types of taxonomic relationships are paraphyletic groups, monophyletic groups, and polyphyletic groups.

- Bulleted items are choices for questions Protists, as a group, represent one of the kingdoms of organisms in the eukaryotic domain. In the other kingdoms, the organisms grouped within a kingdom are very closely related and share many unifying features. The many different organisms grouped as protists are not necessarily closely related, and many different types of traits are represented among them. Review the following list of statements, and select which statements are correct descriptions of protists. Check all that apply. Protists represent both heterotrophic and autotrophic nutritional modes. Some protists are colonial. No protists are multicellular. The phylogenetic tree displayed here shows the evolution and relationships between different major protist groups, as scientists currently understand them. It also shows how these different groups of protists are related to animals, fungi, and land plants.

- Lab 10: Kingdom Animalia Introduction Animals all share some characteristics: 1) Multicellular 2) Heterotrophic 3) Their cells have no cell wall 4) At some time in their life they are motile. There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…arrow_forwardMembers of the kingdom Protista differ from members ofthe kingdom Monera mainly due to the presence of:(a) RNA(b) Ribosomes(c) Cell wall(d) DNA(e) Membrane-bound nucleusarrow_forwardFind the large nucleus located near the cell.

If there are Paramecia in your field of view you probably will recognize them immediately. Often, however, students do have difficulty both finding a Paramecium, and after they have found one, making it move slowly enough so they can study it at high magnification. The trick to finding a Paramecium is to scan the entire slide quickly using the scanning lens. Then, if you do not find one, make a new slide and search again. Often, Paramecia tend to move to the edges of the coverslip, and even "escape" the coverslip at its edges. The trick to slowing the Paramecia is to mix a drop of methyl cellulose with a drop of the cell culture, as…arrow_forward
