- 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! Discuss protist evolution, including an overview of the major groups, and the breadth of variations that occur within this paraphyletic clade. How did protists lead to the evolution of the rest of life on Earth?Why are protists not all grouped together into a single eukaryotic supergroup? Their modes of reproduction are extremely diverse. They do not all possess the same mitochondria structure. They did not all evolve from a shared common ancestor. Their DNA sequence is not identical. They fulfill many different ecological roles. They are found in a variety of habitats.A) A major difference between eukaryotic cells and prokaryotic cells is that eukaryotic cells Group of answer choices exhibit little if any compartmentalization of function are generally smaller than prokaryotic cells have a large degree of internal organization lack organelles have little if any internal organization B) Which of the following statements about protists is false? Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as well
- Which of the following explains why protists are considered a paraphyletic group? A Protists are prokaryotic. B Protists cannot be a monophyletic group because their morphology and behavior are so variable. C Protists lack a common ancestor. O D The MRCA of the protists also gave rise to plants, animals, and fungi. O E Choices B and D are both correct.1. How do members of Eukarya differ from the prokaryotic groups of Chp 26 (your text lists 4 major differences)? Do these differences represent a greater success and superiority of eukaryotic over prokaryotic cells? 2. Examine Figure 27.1 from your text. How does this phylogenetic tree show that "Protists" are paraphyletic? Hint: think about what the term "paraphyletic" means in your answer.. 3. Describe at least two impacts that protists have on humans and two ecological importance's protists have on the planet. 4. What is direct sequencing and how has it been used to discover new lineages in the eukaryotic group? Be specific! 5. What is the endosymbiosis theory and what are thought to have been the three main steps in the theory? What are thought to have been the two main steps in the nucleus formation? • Previous Next MacBook Pro G Search or type URL 23 %24 &50) Some protists, formerly united as the ʺamitochondriateʺ clade, have recently been shown to be rather diverse. 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…

(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 pondsWhy is 'protists' considered a polyphyletic grouping? Why do biologists still use it?Protists are(a) single-celled eukaryotes.(b) multicellular eukaryotes.(c) single-celled prokaryotes.(d) single-celled akaryote.

- 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 following processes are involved in thereproduction of protists ?(a) Binary fission and budding(b) Cell fusion and zygote formation(c) Spore formation and cyst formation(d) All of the above Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.5)Which of the following observations constitutes evidence that mitochondria evolved before chloroplasts? Mitochondria are aerobic. Chloroplasts are photosynthetic. Aerobic bacteria evolved before photosynthetic bacteria (cyanobacteria). Some protists have separately evolved their own plastids (chloroplast-like structures) through endosymbiosis of cyanobacteria, or even through endosymbiosis of photosynthetic protists. All Eukaryotes have mitochondria; only a subset of Eukaryotes have chloroplasts.
