The chloroplast genome of most photosynthetic eukaryotes is roughly 5% the size

Question

The chloroplast genome of most photosynthetic eukaryotes is roughly 5% the size of the genome of the cyanobacterium from which it is thought to have been derived. In comparison, the genome of a photosynthetic amoeba chloroplast from P.chromatophora is roughly 30%-50% the size of the cyanobacterium from which it is thought to have been derived. Does this information suggest that P.chromatophora and other photosynthetic eukaryotes share the same history in terms of evolutionary progress? Why or why not?

Explanation / Answer

Yes P chromotophora and other eurokytes have the same evolution as they have the same and single origin .They all have a single origin of plastids.Some are bigger in size and some are smaller.The size different but origin is same..Moreover the eukaryotic machines of photosynthesis are plastids which are basically evolved from cyanobacteria through primary endosymbiosis
