Noun
endosymbiosis (plural endosymbioses)
(ecology) The condition of living within the body or cells of another organism; an instance of an organism so living.
Disturbance was common in the early stages of endosymbiosis, however, once the host cell gained control of organelle division, eukaryotes could evolve to have only one plastid per cell. Source: Internet
Further evidence of endosymbiosis are the prokaryotic ribosomes found within chloroplasts and mitochondria as well as the double-membrane enclosing them. Source: Internet
Chloroplasts that are the product of secondary endosymbiosis may have additional membranes surrounding these three. Source: Internet
For example, in the initial stages of endosymbiosis, due to a lack of major gene transfer, the host cell had little to no control over the endosymbiont. Source: Internet
One possible secondary endosymbiosis in process has been observed by Okamoto & Inouye (2005). Source: Internet
Primary endosymbiosis Primary endosymbiosis Primary endosymbiosis A eukaryote with mitochondria engulfed a cyanobacterium in an event of serial primary endosymbiosis, creating a lineage of cells with both organelles. Source: Internet
