Endosymbiosis

Endosymbiosis is a process by which two organisms live in close physical association with one another, resulting in a mutually beneficial relationship. It is the basis of the origin of certain organelles, such as mitochondria and chloroplasts, which are essential to life in many organisms today. Endosymbiosis has played a significant role in the evolution of complex life forms, as it enables a variety of processes that could not occur otherwise. Endosymbiosis can also be found in many mutualistic relationships, such as those between plants and their pollinators, mycorrhizal fungi and vegetation, and other organisms. Endosymbiosis is an important part of biodiversity and ecosystem function, as it allows organisms to create novel ways to interact and co-exist with one another.
