MITOCHONDRIA

Definition

 

any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes ;  organelle in which ATP generation occurs; often termend "powerhouse of the cell"
