If an ancestral protist was classified as an opisthokont, then what should be true of this protist? -They should also have given rise to the plants. -They should perform heterotrophy by secretion of exoenzymes. -Like diplomonads and parabasalids, they should bear multiple flagella. -They should be parasitic -They should be the common ancestor of the basidiomycetes and animals.
The prtists that causes malaria evolved from a photosynthetic ancestor and has the remnant of a chloroplast. The organelle no longer functions in photosynthesis, but it remains essential to the protist. Why might targeting this organelle yield an antimalarial drug that produces minimal side effects in humans?
Which of the following is not true of the protists? (a) they are unicellular, colonial, coenocytic, or simple multicellular organisms (b) their cilia and flagella have a 9 + 2 arrangement of microtubules (c) they are prokaryotic, as bacteria and archaea are (d) some are free-living, and some are endosymbionts (e) most are aquatic and live in the ocean or in freshwater ponds
What are one of the main traits that make bacteria and archae unique in comparison to protists, fungi, amáinala and plants? - they have RNA -fungi have chitin - they are single called organismos that do not have membrane bound organelles or bucked - they diverged 3 billion years ago from each other - they have glycolysis
Some molecular evidence suggests that the sister group of animals is not the choanoflagellates, but rather a group of parasitic protists, Mesomycetozoa. Given that these parasites lack collar cells, can this hypothesis be correct? Explain.
Some non-plant organisms like the protist that spreads malaria contain a non-photosynthetic chloroplast called an apicoplast. Crazy! What best explains how protists have evolved apicoplasts?
A group of environmentalists is studying the effects of recent commercial zoning to wildlife acreage on the biodiversity of a rural county. The group noted a steady decline in the population of animals, while bacteria and other protists remained constant. Which statement best discusses the reasons for the steady decline of animals as opposed to the protists? A. Bacterial growth is usually not affected by environmental changes because of asexual reproduction. B. The animals could not adapt to the new environment. C. Bacteria lived in areas that were not affected by the zoning D. The animals became susceptible to human and environmental harm.
DNA sequence data for a diplomonad, a euglenid, a plant, and an unidentified protist suggest that the unidentified species is most closely related to the diplomonad. Further studies reveal that the unknown species has fully functional mitochondria. Based on these data, at what point on the phylogenetic tree in Figure 1 did the mystery protist’s lineage probably diverge from other eukaryote lineages? Explain.
which of the statements is not true regarding protist? a. they may have cell walls b. They may be photosynthetic c. they may be prokaryotic d. they are usually aerobic though some are not e. some are unicellular
Test Your Understanding 1. Which of the following is not true of the protists? (a) they are unicellular, colonial, coenocytic, or simple multicellular organisms (b) their cilia and flagella have a 9 + 2 arrangement of microtubules (c) they are prokaryotic, as bacteria and archaea are (d) some are free-living, and some are endosymbionts (e) most are aquatic and live in the ocean or in freshwater ponds
I don't understand this practice bio question: Despite the fact that modern taxonomists have abandoned the Kingdom Protista, the term "protist" persists in the biological literature. Explain the current meaning of the term protist and give several specific examples.
Some protist lineages arose from secondary endosymbiosis. Howmany membranes would surround the chloroplasts of theseorganisms?a. 0 c. 2b. 1 d. 3 or more
