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.
