The endosymbiont theory is an evolutionary theory that describes the origin of important characteristics of the eukaryotic cells. The theory was first introduced by the Russian botanist Konstantin Mereschkowski in 1905. According to the endosymbiont theory, two of the most defining characteristics of the eukaryotic cells, the mitochondria and the chloroplasts, evolved through symbiosis of individual single-celled prokaryotes.
The first step of the symbiosis is the formation of the nucleus and the endoplasmatic reticulum in the proto-eukaryotic cell, through the infolding of the plasma membrane.
The second step is the evolving of bacteria into mitochondria.
The third step is the evolving of the photosynthetic bacteria into chloroplasts.
Finally, the modern photosynthetic eukaryotic plant cell with the necessary organelles for photosynthesis (chloroplasts) is formed.

Answer from: Quest

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.
