One theory is that eukaryotes have evolved through processes in which different types of free organism prokaryotes are integrated into larger prokaryotic cells and ultimately develop into mitochondria, chloroplast and perhaps other organelles That's what it means.

For over 100 years, the theory of symbiosis symbiosis has considered the difference between prokaryotic cells and eukaryotic cells. In order to explain the origin of eukaryotes and their mitochondria, more than 20 different versions of internal symbiosis theory are proposed in the literature. There are few models that can explain eucaryotic anaerobic bacteria. The role of energy and the energy limitation of prokaryotic tissue for evolutionary innovation in cellular history have recently influenced the theory of internal symbiosis. Only cells with mitochondria have bioenergetic means to obtain the complexity of eukaryotic cells, which is why there is no true intermediate in the transition from prokaryotes to eukaryotes. In the current internal symbiosis theory, it is thought that the host is not an eukaryote but an archaebacter (archaea). Therefore, the history and biology of the archaeal evolution have increased dependence on eukaryotes more than ever.
The theory of symbiosis symbiosis is a unified widely accepted theory about how organelles are produced in living organisms different from eukaryotes. In the theory of internal symbiosis, consistent with the general theory of evolution, all creatures come from a common ancestor. Such ancestry may be similar to bacteria or prokaryotes in which single-stranded DNA is surrounded by the plasma membrane. Over time, the morphology and function of these bacteria have differentiated. Some bacteria acquire the ability to process energy from the environment in a novel way. Photosynthetic bacteria have developed a route to produce sugar from sunlight. Other organisms developed a new way to use this sugar, which is oxidative phosphorylation. And it produces ATP and oxygen from glycolysis. You can then use ATP to supply energy to other reactions within the cell.
