The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein. ... Prokaryotes lack mitochondria and chloroplasts.

Drupady [299]

The question is incomplete. The rest of the question is : Which of these is not supported by the endosymbiosis theory concerning organelles?

A) contain DNA.

B) contain ribosomes.

C) are capable of living independently.

D) are surrounded by a double membrane.

Answer:

Option C) are capable of living independently  is not supported by the endosymbiosis theory concerning organelles

Explanation:

The endosymbiosis theory proves that chloroplasts and mitochondria were prokaryotic cells before due to many reasons. Some of which are:

  • These organelles have their own separate DNA.
  • The separate DNA present in them is capable of making their own proteins.
  • They are membrane- bound organelles.

However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which  occurred in these cells during the long period of time.
