Question

Similarities between Mitochondria and Bacteria

Answer 1

All bacteria have a plasma membrane, most also have a cell wall and while some have a capsule, others do not (1). Some bacteria also have flagella which are tiny whip-like structures often located at one end of the cell. Although they vary in size greatly, common bacteria such as Escherichia coli are about 2μm in length, when comparing this to mitochondria they are very similar in length but like bacteria, the shapes and sizes of mitochondria vary significantly depending on what species or cell they are found in.
Mitochondria are located in the cytoplasm of both animal and plant cells; they are cylindrical structures that consist of an outer membrane, inner membrane and matrix. Like bacteria, mitochondria also have their own circular DNA genome which is separate from the nucleus of the cell which is located in the matrix. The membrane of the mitochondria is also very similar to the membrane found around the bacteria; it is double layered and is made up from lipids, just like a prokaryotes membrane
The main function of bacteria, like any organism, is to reproduce, and while mitochondria's main function is to produce energy in the form of ATP it also needs to reproduce. Mitochondria are formed by a process very similar to binary fission, the method by which bacteria divide.

Answer 2

Similarity: I think the most common and only similarity bacteria and mitochondria has is that they both contain their independent DNA or genetic material.

Otherwise, mitochondrion is a double membrane organelle present in Eukaryotic cells whereas a bacterium is a prokaryotic cell has no double membrane bounded organelle.

Bacterium itself is an individual cell whereas mitochondria is an organelle of a cell.
