What is mythocondria?

Answer 1

I assume you mean mitochondria. Mitochondria are one of the most important organelles of an eucariotic cell(cell of all living creatures except bacterias). It is called power house of cell because it produces energy. The oxigen we breathe is converted into energy by basically mitochondria. So an organelles that produces energy in cells is mitochondrion(in plural it is called mitochondria)

Answer 2

I'm not familiar with that term. Did you mean "mitochondria"? Mitochondria are known as the powerhouse of the cell, producing energy in the form of ATP through a process called cellular respiration. They have their own DNA and are believed to have originated from ancient bacteria through an endosymbiotic relationship.
