Mitochondria and chloroplast are
(A) semi-autonomous organelles
(B) formed by division of pre-existing organelles and they contain DNA but lack protein synthesising machinery.
Which one of the following options is correct?
Mitochondria and chloroplast are semi-autonomous organelles and formed by division of pre-existing organelles. They contain DNA and protein synthesising machinery (70S ribosome). They synthesise some of the proteins and also receive some proteins from cytoplasm (semi-autonomous).
