Statement $$1$$: Chloroplast and mitochondria are semi-autonomous bodies. Statement $$2$$: Chloroplast and mitochondria have their own DNA and protein synthesising machinery.
ABoth statements $$1$$ and $$2$$ are correct
Correct Answer
BStatement $$1$$ is correct but statement $$2$$ is incorrect
CStatement $$1$$ is incorrect but statement $$2$$ is correct
DBoth statements $$1$$ and $$2$$ are incorrect
Solution
Chloroplasts and mitochondria are semi-autonomous cell-organelles possessing their own DNA and proteins. In animals, an individual gets mitochondria and mitochondrial genes from its mother because the middle piece of a sperm that contains mitochondria does not enter the egg during fertilisation. This inheritance pattern of mitochondrial genes is called uniparental inheritance or extranuclear inheritance or maternal inheritance.
So, the correct answer is 'Both statements 1 and 2 are correct'.
