They both absorb nutrients from their environment. As an environmental scientist, what would you suggest concerned citizens do to help prevent these red tides? The macronucleus divides into two with each new cell receiving an identical macronucleus. B. Rhizaria -The organisms that feed on decomposers would not have a food source. Distinctive strawlike hairs occurring on the surface of flagella are characteristic of: Opisthokonta Excavata Alveolata Rhizaria Stramenopila Stramenopila How do members of the Amoebozoa move? A. A. extinction of species.

A. protecting the flagellum B. filtering bacterial food D. half-decay A. Opisthokonta E. flagellates, Which protist would most likely be phytoplankton? The tripartite hairs have been lost in some stramenopiles - for example in most diatoms (although these organisms still express mastigonemic proteins - see below). How did the earliest single-celled microorganisms produce energy to drive metabolic processes? It allows scientists to prevent meiosis and the E. They attach to host cells by small hooks. C. archaeal ancestors [29] transfer of spores The supergroup Excavata contain some of Earth's most recent eukaryotes. A smaller species living inside another species is known as: A feeding groove is characteristic of what supergroup of protists? D. cyanobacteria the other choices provided, A. emission of flashes of light by organisms. T or F, Sushi wrappers called nori are a type of red algae. A. of the following statements DOES NOT describe its attributes? D. It can occur through endosymbiosis. Both frustules are replaced by individuals that are formed sexually. produce two, (4) of which one stays in the parent cell and the other T or F, Slime molds are in the supergroup Group: Stramenopiles Oomycetes (Water Molds and Their Relatives) Oomycetes include water molds, white rusts, and downy mildews They were once considered fungi based on morphological studies Most oomycetes are decomposers or parasites They have _____ _ (hyphae) that facilitate nutrient uptake The anterior flagellum (usually) has one or two rows of glycoprotein appendages calledmastigonemes. pseudopodia B. possession of hard shells C. tertiary What is the most accurate description of the consequence(s) of the increased oxygen (O2) in the atmosphere during and after the Silurian Period? bacterium, Flagella can be used to: A.propel the organism through C. osmotrophic D. autotrophic E. mixotrophic. disintegrate, (3) the remaining micronucleus undergoes mitosis to when organic food is abundant, With regard to protists, what is a cyst? Excavata D. autotrophic They joined other heterotrophic protists, such as bicosoecids, labyrinthulids, and oomycete fungi, that were included by some as heterokonts and excluded by others. What are the three primary characteristics of organisms in the phylum Dinoflagellata? [Solved] Stramenopiles Are Unique in That They Possess [35][36][37], Platysulcidae Shiratori, Nkayama & Ishida 2015, Placididea Moriya, Nakayama & Inouye 2002, Opalinea Wenyon 1926 emend. A. the choanoflagellates D. The macronuclei fuse with the Cercozoa also includesPaulinella chromatophora,a unicellular photoautotroph whose plastid represents a possible instance of primary endosymbiosis. Listeria monocytogenes is a species of rod-shaped bacteria. Most are unicellular and have a zygotic cycle. - Pleodorina californica red algae Each half of a diatom cell wall is called afrustule, with one frustule slightly smaller than the other and the two fitting together and joined by a protein band. A. E. are all more closely related to fungi than they are to any other organisms, The collars on the cells of choanoflagellates have the function of: B. Plasmodium falciparum is a protistan parasite, borne by The genome of a Blastocystis subtype 7 was resolved by pulsed-field gel electrophoresis, and 15 chromosomic bands have been characterized. pathogen. E. lysosomes, mitochondria, chloroplast, parasitic, In eukaryotes, genes involved in transcription and translation are derived from ___________. saprobes. D. Giardia lamblia The unifying feature of this group is the presence of a textured, or "hairy," flagellum. Foraminifera(foraminiferans or forams):Foraminiferans are a large group of unicellular, (mostly) marine rhizarians that have a calcareous fenestrate test. Why or why not? E. Participate in beach cleanup efforts, Phagotrophy (Phagocytosis) is: D. gametocytes C. the synthesis of organic molecules from inorganic molecules using light as an energy source cramps C. diarrhea and dehydration D. headaches and The mushrooms illustrated at the end of the video exhibit what kind of life style? The chemical composition of the gases surrounding the Earth has changed substantially over the past 4 billion years. Study with Quizlet and memorize flashcards containing terms like Sponges (phylum: Porifera) are animals that possess feeding cells called collar cells. B. kingdoms Many stramenopiles are unicellular flagellates, and most others produce flagellated cells at some point in their lifecycles, for instance as gametes or zoospores. Eukarya and Archaea diverged from a common ancestor more recently than they diverged from their common ancestor with Bacteria. (Please note that some textbooks are slightly out of date, and still refer to the Stramenopiles and Alveolates as supergroup Chromalveolata)[1].
