The Photosynthetic Eukaryotes

The photosynthetic eukaryotes

A) form a monophyletic group because it appears likely that a single endosymbiotic event produced the many different-coloured chloroplasts observed in protists and plants.
B) contain chloroplasts that have evolved from the cyanelles of Glaucophytes.
C) share an acquired organelle rather than a common ancestor.
D) have diverged into three distinct lineages: the 'green lineage' (green algae and plants) , the 'brown lineage' (brown algae, diatoms and other chromists) , and the 'red lineage' (red algae and dinoflagellates) .
E) All the answers are correct.
