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.

(Alga is the singular of algae.) How do these two types of organisms work together to become a functional composite organism? That is, what does each organism provides to the relationship to make it successful? Think about a lichen living on the face of a rock.arrow_forward
