Endosymbiosis is one of the most important evolutionary events is cells over time. At one time all cells were prokaryote and then by ingestion, or invasion other cells entered some cells and stayed to become part of a more complex cell that could divide cellular labor more efficiently. This is how the mitochondria came about and this organelle was once it's own cell and still has it's own circular DNA.

How have mitochondria and chloroplasts have evolved?
Mitochondria and chloroplasts are thought to have evolved from ancient symbiotic bacteria that were engulfed by early eukaryotic cells. Over time, these bacteria formed a symbiotic relationship with the host cells, with the bacteria providing energy (mitochondria) or photosynthesis capabilities (chloroplasts) in exchange for protection and nutrients. This symbiosis eventually became permanent, leading to the development of these organelles within eukaryotic cells.
How did cell theory change over time?
Cell theory changed over time as new discoveries were made. Originally proposed in the 1830s, the theory evolved to include the understanding that cells are the basic unit of life, that all living organisms are made up of cells, and that cells come from pre-existing cells through cell division. More recent advancements have also revealed the complex structures and functions within cells.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.
What role does the endosymbiont theory play in explaining the origin of eukaryotic cells?
The endosymbiont theory explains that eukaryotic cells evolved from a symbiotic relationship between different types of prokaryotic cells. This theory suggests that mitochondria and chloroplasts, which are organelles in eukaryotic cells, were once independent prokaryotic cells that were engulfed by a larger host cell. Over time, these prokaryotic cells became integrated into the host cell and eventually evolved into the organelles we see in eukaryotic cells today. This theory helps to explain the presence of these organelles in eukaryotic cells and provides insight into the evolutionary history of these complex cells.
What is the current understanding of how mitochondria and chloroplasts arose, and how has this knowledge evolved over time?
Mitochondria and chloroplasts are believed to have originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. This theory, proposed by Lynn Margulis in the 1960s, suggests that these organelles were once independent organisms that formed a symbiotic relationship with their host cells. Over time, these organelles became integrated into the cells and evolved to perform specific functions, such as energy production in mitochondria and photosynthesis in chloroplasts. This theory has been supported by molecular and genetic evidence, and is now widely accepted in the scientific community.
