- Which clade does not have protists as members? Chromalveolata Excavata Unikonta Archaeplastida none of these are correctWhich of the following structures in chlorarachniophytes provides evidence that they evolved through the endosymbiosis of a green alga by a heterotrophic eukaryote? A. food vacuole B. nucleomorph C. mitosomes D. flagellaExcept for the Plantae, what best describes the origin of chloroplasts in most other eukaryotes? Group of answer choices Chloroplasts evolved independently in different lineages Primary endosymbiosis An amoeboid protist engulfed another protist that had chloroplasts in its tissues Mitochondria were converted to perform photosynthetic functions Eukaryotes outside the Plantae don’t have chloroplasts
- 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 itModern 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.one of the following is the ancestor of the plant kingdom golden algae radiolarians foraminiferans apicomplexans non of the above

Group of answer choices protists algae bryophytes seed plants seedless vascular plantsHow 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?
