FranThe endosymbiotic theory includes the idea that mitochondria and chloroplasts were once free-living prokaryotic cells that were engulfed by larger cells and developed a symbiotic relationship, leading to modern eukaryotic cells. It does not include the concept of gene flow between mitochondrial and nuclear genomes.

The endosymbiotic theory was supported by the scientist?
Lynn Margulis was the scientist who proposed and championed the endosymbiotic theory. She provided evidence to support the idea that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms.
When was the endosymbiotic theory proposed?
The endosymbiotic theory was proposed in the 1960s by Lynn Margulis to explain the origin of eukaryotic cells. It suggests that eukaryotic cells evolved through a mutually beneficial relationship between primitive prokaryotic cells.
Endosymbiotic theory explains the formation of organelles surrounded by how many membranes?
Endosymbiotic theory explains the formation of organelles surrounded by two membranes. This theory suggests that eukaryotic organelles such as mitochondria and chloroplasts originated from symbiotic prokaryotic cells that were engulfed by a host cell, leading to a mutually beneficial relationship.
What are the 3 main steps of the endosymbiotic theory?
The three main steps of the endosymbiotic theory are: 1) the engulfment of a prokaryotic cell by a larger host cell, 2) the establishment of a symbiotic relationship between the two cells, and 3) the evolution of the endosymbiont into an organelle within the host cell.
What are the two theories of evolution in a eukaryotic cell?
The two theories of evolution in a eukaryotic cell are endosymbiotic theory and gene duplication. Endosymbiotic theory suggests that eukaryotic cells evolved from a symbiotic relationship between different prokaryotic organisms. Gene duplication theory suggests that gene duplication events have played a significant role in the evolutionary development of new functions and complexity in eukaryotic cells.
