Which characteristic do all prokaryotes and eukaryotes share?

Prokaryotes are cells that lack a nucleus or membrane organelles.

Eukaryotes are either single-celled or multicelled cells that contain membrane-bound organelles like the nucleus.

But both have the following characteristics.
1) They both have DNA as their genetic material
2) They are membrane bound (prokaryotic cell walls are made of peptioglycan while eukaryotic cell walls are made of glycogen)
3) They both contain ribosomes
4) They have similar basic metabolism
5) They are diverse in forms.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
