Mitochondria and chloroplast are I. semi-autonomous organelles. II. formed by the division of pre-existing organelles and they contain DNA but lack protein synthesising machinery. Which one of the following options is correct?
They have DNA and 70S ribosomes, so they do synthesise proteins.
Mitochondria and chloroplasts are called semi-autonomous organelles because they have their own DNA and 70S ribosomes.
They are formed by division of pre-existing organelles and can synthesise their own proteins, so statement II (lack protein-synthesising machinery) is false.
