Are chloroplasts only in eukaryotic cells?

Question

Although some prokaryotic organisms can carry out photosynthesis, are chloroplasts only found in eukaryotic cells ?

Answer 1

Yes, they are only found in eukaryotic cells. The bacteria have other pigments that work as chlorophyll.

Answer 2

braveheart is wrong!  Although some prokaryotic organisms have photosynthesis, they do not have chloroplasts.  Chloroplasts are found only in eukaryotic organisms.

Answer 3

Of course not. Chloroplasts are also found in prokaryotes such as photosynthetic bacteria. It had been found out that the pigments as well as the mechanism of photosynthesis is similar except for some processes and pigments. According to the Endosymbiotic Theory, chloroplasts are once on their own (bacteria that can carry on photosynthesis) suggestive that the chloroplast is not exclusive to the eukaryotes. in fact the primitive chloroplast is exhibited by bacteria. Same is true with the mitochondria.

Answer 4

Yup...chloroplast only been found in eukaryotic cells. why? well some evolution experts said that choloroplast was originally a single celled photosynthetic bacteria (or at least prokaryotic cell) that invade inside the body of an eukaryotic cell (just like virus). but then they found a way to cooperate and evolve together (called co-evolution) to benefit each other so the became one cell. the convincing proof is tha chloroplast has their own DNA, despite the nuclear DNA.
