What evidence supports the theory of endosymbiosis? Mitochondria and chloroplasts are similar to prokaryotes they do not have theh own membranes Eukaryotic cells contain mitochondria and some contain chiorophyll. contain ribosomes. Mitochondrial DNA is most closely related to a parasitic bacteria called Rickettsia prowazekit, causes epidemic typhus. Both mitochondria and chloroplasts have a circular DNA genome, like a bacteria's genome, but smaller. This DNA is passed from a mitochondrion to its offspring and separate from the host" cell's genome in the nucleus. Both mitochondria and chloroplasts have their own ribosomes to produce proteins. Eukaryotic cells were on earth before prokaryotic ones.

Both mitochondria and chloroplasts have a circular DNA genome, like a bacteria's genome, but smaller.

Explanation:

The theory of endosymbiosis explains how eukaryotic cells might have risen from prokaryotic cells.

The evidence which supports this theory was the fact the organelles like mitochondria and chloroplast have their own DNA, which is like the prokaryotic DNA. It is circular and smaller. This DNA is also capable of making its own RNA.

This evidence supports the theory of endosymbiosis.
