Answer #1

According to the accepted theory of the origin of eukaryotic cells, the mitochondrion originated from an aerobic heterotrophic bacterium. This is from the endosymbiosis theory. This theory states that earlier mitochondria was a separate living organism. Many years ago it was engulfed by an eukaryotic bacteria. There are no fossil records for the evolution of eukaryotic bacteria. Evidence for endosymbiosis comes from DNA sequencing. DNA analysis reveals that eukaryotes possess many bacterial genes. When it comes to size, mitochondria has a similar size as that of bacteria. It divides independent of the eukaryotic host cells by a process called binary fission.

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...
