Hi! human,dog are multicellular organisms. Nucleus,cell membrane, cytoplasm and mitochondria are 4 things that plant and animal cells have.
Mitochondria are made from the process called binary fission. This is the cell division utilized by the prokaryotes. It also has circular DNA that is similar in both size and structure in prokaryotic cells. Mitochondria also has its own DNA different than the DNA found in the nucleus of a cell.
They are different because they use different frequency
