in 1909 the russian lichenologist konstantin mereschkowski presented a research paper "the theory of two plasms as the basis of symbiogenesis, a new study on the origin of organisms", which aims to explain a new theory of symbiogenesis by lichens and other organisms as evidenced by his earlier work "nature and origin of chromatophores in the plant kingdom". these new ideas can be studied today under the title of the theory of endosymbiosis.

primary endosymbiosis involves the engulfment of a cell by another free living organism. secondary endosymbiosis occurs when the product of primary endosymbiosis is itself engulfed and retained by another free living eukaryote. secondary endosymbiosis has occurred several times and has given rise to extremely diverse groups of algae and other eukaryotes. some organisms can take opportunistic advantage of a similar process, where they engulf an alga and use the products of its photosynthesis, but once the prey item dies (or is lost) the host returns to a free living state. obligate secondary endosymbionts become dependent on their organelles and are unable to survive in their absence.) redtol, the red algal tree of life initiative funded by the national science foundation highlights the role red algae or rhodophyta played in the evolution of our planet through secondary endosymbiosis.
