Group of answer choices Protists are a monophyletic group of organisms All protists are unicellular All protists are photosynthetic Some protists have prokaryotic cells The protist group known as charophytes gave rise to land plantsarrow_forwardWhich of the following correctly matches the protist to the mode of nutrition? Chara- Autotrophy, Euglena - Mixotrophy, Amoeba - Heterotrophy Chara - Heterotrophy, Euglena - Mixotrophy, Amoeba - Heterotropy Chara - Mixotrophy, Euglena- Heterotrophy, Amoeba - Autotrophy They all are capable of Heterotrophyarrow_forwardThe following are actual mutualistic partnerships that involve a protist and a host organism; which is the exception? Trichomonas and humans Cellulose-digesting gut protists and wood-eating termites Protists living in hypersaline /anoxic waters always associated with bacteria Algae and certain foraminiferans Photosynthetic dinoflagellates and reef-building coral animalsarrow_forward
- 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.arrow_forwardWhich of the following plant-like protists exhibits behavior of both plants and animals? Group of answer choices euglenoids algae diatoms dinoflagellatesarrow_forwardWhat is the best way to describe this organism. Eukaryote, prokaryote, animal-like Prokaryote, protist, plant-like Eukaryote, plantae, plant-like Prokaryote, plantae, protist-like Eukaryote, protist, plant-likearrow_forward
- Which of the following is an example of fungus-like protist? Group of answer choices golden algae rhizopus plasmodial slime molds trufflesarrow_forward#3 Why don't we consider protists to all be in 1 kingdom together anymore? Group of answer choices: 1.because some of them are multicellular 2.because they are all prokaryotic 3.because some of them are prokaryotic 4.because they are not all closely relatedarrow_forwardA principle of biology is that biology affects our society.

- Research an interesting example of mutualism, and present your findings in a post. The goal here is to provide examples beyond what is presented in lecture and/or your textbook. These can be animal-animal, animal-fungal, plant-fungal, plant-animal, bacteria-animal....the sky is the limit! For this particular forum, you'll be able to see other classmates postings even before you post your own. This is so you can present an example that's different from what's already been discussed. Remember that mutualistic interactions are associations that benefit both parties -- so your response should clearly indicate the role each partner plays. Let us know where these organisms are found, what kind of habitat they live in, and any other interesting , pertinent information. Also, please comment on how natural selection likely played a role in the development of your example. You can use your imagination a bit here -- I'd just like to see you connect the ideas. Your posting must be at least…arrow_forwardWhich 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.arrow_forwardProtists are a diverse group of eukaryotic microorganisms. Which of the following are types of protists? (Select all that apply) Algae Protozoa Fungi Bacteria Slime moldsarrow_forward
