Mitochondria and chloroplasts used to be free-living. They used to be prokaryotes, but they got enveloped by other prokaryotes and their membrane became a double membrane because the first one stayed and the second one came from it being enveloped. Their DNA is also similar to prokaryote DNA. Their original cell membrane is also similar to a prokaryote's cell membrane.

What 2 dna-containing organelles support Margulis theory of endosymbiosis?
The two DNA-containing organelles that support Margulis' theory of endosymbiosis are mitochondria and chloroplasts. These organelles contain their own DNA, which is separate from the nuclear DNA of the cell, and share some similarities with bacteria, indicating that they were once free-living prokaryotic organisms that were engulfed by a host cell and formed a symbiotic relationship.
What part of the cell theory did Lynn margulis contribute to?
She concluded that some organelles found in eukaryotes were once free-living prokaryotes.
What is the evolutionary hypothesis that some organelles are remnants of prokaryotic cells?
The endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic cells that were engulfed by a host cell through endocytosis. Over time, these prokaryotic cells formed a symbiotic relationship with the host cell, eventually evolving into permanent organelles within the eukaryotic cell.
What organelle may survive and reproduce independently of a cell?
Mitochondria are organelles that were once free-living bacteria. They can survive and reproduce independently in certain conditions, suggesting they have retained some autonomy from the host cell.
What is another theory for the formation of organelles?
Endosymbiotic theory proposes that some organelles, such as mitochondria and chloroplasts, were once free-living prokaryotic organisms that were engulfed by a larger host cell, forming a symbiotic relationship over time. This theory is supported by the presence of unique DNA within mitochondria and chloroplasts, as well as their ability to replicate independently within the cell.
Which organelles were once free-living protists that got eaten but not digested by larger cells?
chloroplasts; mitochondria
How is cell evidence for evolution?
the presence of organelles like the lysosome and the mitochondrion which both have double membranes. this suggests that these organelles were once free-living organisms that were incorporated into a larger organism in what could be called a mutual symbiosis.
Two organelles that are believed to be descendants of unicellular bacteria are?
Two organelles that are believed to be descendants of unicellular bacteria are mitochondria and chloroplasts. The endosymbiotic theory suggests that these organelles were once free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
What 2 dna-containing organelles support Margulis theory of endosymbiosis?

Over time, these prokaryotic cells formed a symbiotic relationship with the host cell, eventually evolving into permanent organelles within the eukaryotic cell.
Who said that organelles where once cells themselves?
Lynn Marguils and she said it in 1970.
Does Just Cause 2 have free roam?
Once you have completed the first 2 missions on Just Cause 2, you can do what you want. So yes, Just Cause 2 does have free roam.
Is there free play in saints row 2?
yeah once you beat the game
What organelle may survive and reproduce independently of a cell?
Mitochondria are organelles that were once free-living bacteria. They can survive and reproduce independently in certain conditions, suggesting they have retained some autonomy from the host cell.
Can you charge two ipods at once?
yes, if you have 2 USB cables and 2 free USB slot on your computer.
