You are digging for fossils and found an ancient one with well preserved cellular contents. After testing in the lab, you realize that the cell wall of the fossilized species contains cellulose. This means that the most likely group of organisms to which this fossil belongs isgreen plants and fungi animals and algae green plants and algae protists

Fungi and Animals are distantly related to each other. One trait animals and fungi share however is; Both groups are immobile Both groups undergo an alternation of generations Both have heterokaryotic cells Both groups are heterotrophs
Modern taxonomic treatments rely heavily on phylogenetic data to classify organisms. In the past, taxonomists often used a morphological species concept, in which species were defined based on similarities in growth form. Give an example of how a morphological species concept would group a set of protists differently from how a phylogenetic species concept would.
Compare the phylogenetic tree of protists with the secondary endosymbiosis theory which proposes how photosynthetic protists evolved. Are both reconcilable? Explain.
You are diving off the coast of an island. Since you are a very good diver, you can go quite deep. Once you stop descending, you look around at the life forms. You notice what you think is an algae. Knowing what you know about algae and their ability to undergo photosynthesis, what phylum of algae are you most likely looking at? -Phylum Bacillariophyta -Phylum Chlorophyta -Phylum Phaeophyta -Phylum Chrysophyta -Phylum Rhodophyta
Fungi and animals are both part of a group called Opisthokonta. The vast majority of fungi are multicellular. However, their sister taxon consists of unicellular species. Animals also are multicellular and their closest relatives are again unicellular. Briefly describe the two hypotheses that could explain the origin of multicellularity in the Opisthokonta, and then explain which of the two is the more likely hypothesis
Carotenoids in algae have evolved through primary and secondary endosymbiosis. provide a well-constructed phylogenetic tree to show where carotene, neoxanthin, zeaxanthin, violaxanthin, fucoxanthin, and lutein arose in the macrophytic, multicellular groups of algae. add descriptive and informative title to it
Green algae are believed to be the ancestors of the bryophyte. Cite four distinct lines of evidence to support this belief.
You are on a hike and collect an interesting organism. You carefully examine and research the organism and discover that it is multicellular, heterotrophic and does not have a cell wall. To which kingdom does this organism belong?
Which of the following are correctly arranged in the sequence in which the various taxa first appeared in time? -bacteria, streptophytes, protists, mosses, angiosperms, cycads. -prokaryotes, red algae, streptophytes, mosses, ferns, conifers, angiosperms. -bacteria, protists, liverworts, lycophytes, streptophytes, angiosperms, gnetophytes. -protists, prokaryotes, streptophytes, ferns, mosses, angiosperms, conifers. -prokaryotes, protists, mosses, streptophytes, conifers, ferns, angiosperms.
A student is using a Venn Diagram to communicate understanding of the similarities and differences between fungi and animals. The student placed key characteristics in each circle and classmates are asked to review the work. Fungi Only Animals Only Both May be multicellular or unicellular Eukaryotic Multicellular Can reproduce asexually or sexually No cell wall Has a cell wall Heterotrophic Which feedback would be the MOST accurate? O A. "All animals only reproduce sexually so you need to move 'may reproduce sexually or asexually 'to fungi only." B. "You need to move the term heterotroph to the 'animals' circle because fungi can be heterotrophic or autotrophic." C. "You have all of the information correct." O D. "You should remove 'has a cell wall' because neither fungi nor animals have a cell wall.
How are forams useful for researchers to study changes in ocean temperature over time? What are mixotrophs? What is endosymbiosis and why is it consider to be the source of eukaryotic diversity? Why are we confident this only happens once? What is primary and secondary endosymbiosis? Was there another endosymbiotic event that led to a third lineage? What group of organisms possesses a structure that might suggest this possibility and what is the structure? Why is the structure question different from the ancestor of other plastids? What are diatom blooms and why are they of particular interest to climate change scientists?
Animals and fungi are both heterotrophs, but they have many differences. What are the main differences in structure and function between a Precambrian animal (such as Hallucigenia) and a fungus like a mold.
