I am a double-membraned cell organelle. I produce energy-rich molecules called ATP. I have my own genetic material. Who am I?
The correct option is D Mitochondrion Mitochondria are double-membraned cell organelles present in the cytoplasm. They have their own genetic material. They produce ATP, which are energy-rich molecules. Since they produce energy rich molecules, they are called the 'powerhouse' of the cell.
