Plastids that are surrounded by more than twomembranes are evidence of(A) evolution from mitochondria.(B) fusion of plastids.(C) origin of the plastids from archaea.(D) secondary endosymbiosis.
Molecular fossils further indicate the presence of ciliates and dinoflagellates in the emerging eukaryotic world and show that algae were expanding to become major photosynthesizers in the oceans. How can we explain this diversification?
How many types of plastids are there?

- What alga does a trypanosome superficially resemble?arrow_forwardDNA 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.arrow_forwardThe prtists that causes malaria evolved from a photosynthetic ancestor and has the remnant of a chloroplast.
