Mitochondria: It is also called power house of the cell because it genetates or produces energy for the cell which is required for different functions. The glucose which is absorbed by the body is taken to the cell and from there the glucose is entered in the mitochondria. The mitochondria start break down of the glucose molecule and generates energy in the form of Adenine tri phosphate (ATP).
Eukaryotes are larger cells with membrane-bounded organelles. Prokarotes are not that large and do not have a nucleus or any memberane-bound organelles.
