Mitochondria or powerhouse of the cell is the second-largest organelle in animal cells. They are self-replicating bodies with a life span of 7-10 days. Mitochondria present only in eukaryotic cells except for mature RBCs and anaerobic cells. The number of mitochondria in any cell depends upon the metabolic activities of the cell. For example, the kidney has 300-400 mitochondria, oocytes have 30,000 mitochondria, the liver has 1000-1600 mitochondria and in yeast, it is less than 10. Mitochondria is double-membrane organelle. The outer permeable membrane is stretched tightly and inner selectively permeable membrane form folds called Cristae with a large number of bat-like structures attached called Oxisomes. They are also known as the powerhouse of the cell or storage batteries or ATP mills of the cell. So Take tHis quiz and increase your knowledge about mitochondria or powerhouse of the cell
