Mitochondria are thought to have evolved from ancient bacteria. Free-living bacteria have lost motility in mitochondria over time.

<h3>What is endosymbiosis?</h3>
  • Endosymbiosis is the term used when one organism truly lives inside the other. According to the endosymbiotic theory, it is simple for a big host cell and ingested bacteria to become dependent on one another for survival and develop a long-term bond.
  • Due to their increased specialization through millions of years of evolution, mitochondria and chloroplasts can no longer survive outside of cells.
  • Chloroplasts and mitochondria are remarkably similar to bacterial cells. They have unique DNA that is distinct from the DNA found in the cell's nucleus.
  • Additionally, these organelles synthesize numerous proteins and enzymes necessary for their functions using DNA. Both mitochondria and chloroplasts are surrounded by a double membrane, which is additional proof that each was ingested by a primitive host.
  • Similar to bacteria, the two organelles also divide by themselves and replicate their own DNA.

Bacteria are prokaryotes, fungi and protists are eukaryotic organisms and viruses are not living.

<h3>In what ways it is possible to distinguish prokaryotes from eukaryotes?</h3>

Bacteria (e.g., E coli) are prokaryotic organisms whose cells don't have nuclei or membrane bound organelles, reproduce by asexual ways such as binary fission, and they are beneficial as descomposers.

Some common diseases caused by bacteria include tetanus (Clostridium tetani), pneumonia (Klebsiella pneumoniae), cholera (Vibrio cholerae), etc.

Moreover, protists (e.g. algae) and Fungi (e.g. Saccharomyces cerevisiae) are eukaryotic organisms that have cell nuclei and organelles, can reproduce by asexual reproduction, can perform photosynthesis (algae) or acts as decomposers (fungi).

Some common diseases caused by protists/protozoans include malaria (Plasmodium), sleeping sickness (Trypanosoma), etc.

Some common diseases caused by fungi include aspergillosis (Aspergillus), candidiasis (Candida albicans), etc.

Finally, viruses are not living because they need a host to survive and are also useful as vectors to design gene therapy techniques.

Some common diseases caused by viruses include AIDS (HIV retrovirus), dengue fever (Flaviviridae viruses), etc.

Bacteria are used to produce insulin and other natural medications, viruses are used as carriers for the treatment of diseases,  protozoans can enhance the fertility of soils and fungi are employed in the preparation of foods.

In conclusion, bacteria are prokaryotes, fungi and protists are eukaryotic organisms and viruses are not living.
