Answer:
A mitochondrion is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms. It produces energy, known as ATP, for the cell through a series of chemical reactions
Binary fission is a form of asexual reproduction used by members of domains archaea and bacteria among other organisms. Like mitosis (in eukaryotic cells), it results in cell division of the original cell to produce two viable cells that can repeat the process. Hope I’ve helped ;)
