Sample A - Mitochondria, Sample B - Chloroplast; because both the organelles are double membrane bound structure.
Sample A- Mitochondria, Sample B - Chloroplast; because they both are capable of synthesis of their own proteins only.
Sample A - Mitochondria, Sample B - Chloroplast; because they are capable of synthesis of their own proteins and contain their own DNA.
Sample A- Mitochondria, Sample B - Chloroplast; because they contain their own DNA to transfer the genetic information from one generation to another.
