- Find the large nucleus located near the cell. Make several outline drawings to illustrate the successive changes of 1. shape of the amoeba. Make drawings of the Amoeba you observe, and label its structures. C O O liko mer 0 AS 6 0 O Paramecium -- Paramecia are quite large, straw-colored, slipper-shaped and move rapidly, and they are thus very noticeable. 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…Topic 1: Order Lycopodiales (Club mosses) 1.

Walker and students of Humboldt State University (CC BY-SA 4.0).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. The protist groups are highlighted in tan boxes.…

Some of them possess neither mitochondria nor mitochondrial genes (and have been classified as fungi). Others possess no mitochondria, but do have mitochondrial genes in their nuclear genome. Still others have modified mitochondria (viz. mitosomes or hydrogenosomes). Which statement(s) represent(s) consequences of these recent findings? 1. The amitochondriates do not comprise a true clade. 2. The ʺamitochondriate hypothesisʺ concerning the root of the eukaryotic tree has been strengthened. 3. Just as there is a diversity of cyanobacterial descendants among eukaryotes, so too is there a diversity of alpha-proteobacterial descendants among the eukaryotes. 4. If the amitochondriate organisms continued to be recognized as a taxon, this taxon would be polyphyletic. 5. Horizontal gene transfer involving mitochondrial genes has occurred in some amitochondriate organisms. A) 1 only…
- write in 5 paragraphs Protists are the most varied group of organisms that we studied this term. They display unique adaptations in feeding, reproduction, and lifestyle (parasitism, free living, etc) among many others!
