Assertion : Mitochondria and chloroplasts are independent organelles.
Reason : They are formed by division of pre-existing organelles and contain DNA but lack protein synthesizing machinery.
Assertion (A) is true but reason (R) is false.
Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Answer:
Here's your answer
Explanation:
Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems. ... The prokaryotic ancestors of chloroplasts and mitochondria were endosymbionts whose genes became copied to the genomes of their cellular hosts.
So, option d is the correct one.
Answer:
Hint: Mitochondria and chloroplasts are called semi-autonomous cell organelles as they have their own DNA and ribosomes. Therefore, they can synthesize some of their proteins. For other proteins, they are dependent on the nucleus.
