B)The chloroplasts of red and green algae are the descendants of cyanobacteria.

This statement is false because all eukaryotic cells have mitochondria, which are believed to have originated through endosymbiosis with purple bacteria. Chloroplasts, on the other hand, are believed to have originated through endosymbiosis with cyanobacteria, as stated in option B. While some algae may have acquired chloroplasts through secondary endosymbiosis with other eukaryotic cells, they still have mitochondria. Option A and option E are both true statements about the origin of mitochondria and chloroplasts. Option D is also true, as many of the internal membrane-bound compartments of eukaryotic cells are derived from the endomembrane system.
