HELP AHhHHHhHhHhHH a. Describe the endosymbiotic theory. Explain how chloroplasts are similar to prokaryotic cells.
b. Provide observations and evidence that supports the theory.

The endosymbiotic theory was eukaryotes that evolved to prokaryotes then to other organelles. Chloroplasts are similar to prokaryotic cells because they have a double membrane structures and more. Things that support this theories can be like I said, double membrane structures which both have and  circular DNA and bacteria ribosomes too.

Explanation:

:3

The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.

Explanation:

The exterior structure similar to bacterial cell walls" IS NOT an evidence in favour of the endosymbiotic theory. Both mitochondria and chloroplasts are double membrane bound.

Explanation:

Both the organelles mentioned in your question, are present in eukaryotic cells.

Both mitochondria (the energy producer of the cell) and chloroplast (photosynthetic machinery) have their own circular DNA . (The DNA molecules present in the nucleus of eukaryotic cells are in the form of strings and are not circular. ) We know that circular DNA is more primitive as seen in all bacteria, linear DNA definitely evolved later.

b. heterotroph
