Scientists believe that mitochondria originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, the relationship between the host cell and the engulfed bacteria became mutually beneficial, leading to the evolution of mitochondria as specialized organelles responsible for energy production in eukaryotic cells.

What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
What is common with chloroplast and mitochondria?
They are originated from bacteria.They have ribosomes,DNA,enzymes etc
What is another cell organelle that is thought to have originated through endosymbiosis?
Take the mitochondria as example. This organelle contains it's own circular DNA that is representative of cyanobacterial DNA. This DNA codes for some proteins also. Some mitochondrial DNA has been taken into the nuclear DNA where it's presence is rather obvious. And the mitochondria fission in reproducing themselves.
Two organelles that are believed to be remnants of unicellular bacteria are?
Mitochondria and chloroplasts are two organelles believed to be remnants of unicellular bacteria. Mitochondria are thought to have evolved from aerobic bacteria, while chloroplasts are believed to have originated from photosynthetic bacteria.
What organelles are associated with ednosymbiont theory?
The endosymbiont theory is associated with mitochondria and chloroplasts. It proposes that these organelles originated from primitive prokaryotic cells that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
Where have mitochondria originated from?
They have evolved from bacteria. Aerobic bacteria have turned into them
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
How do some scientists think that the first eukaryotes evolved?
By various bacteria ingesting but not digesting other bacteria, most likely the precursors of mitochondria (and/or chloroplasts).
What pair of organelles are thought to have originated from prokaryotes that were taken in but not digested?
Mitochondria and chloroplasts.
What is common with chloroplast and mitochondria?
They are originated from bacteria.They have ribosomes,DNA,enzymes etc
Who is mew?
mew is the Pokemon that poke-scientists think was the first Pokemon ever. they think all Pokemon originated from mew since it can learn all kinds of moves.
What is another cell organelle that is thought to have originated through endosymbiosis?
Take the mitochondria as example. This organelle contains it's own circular DNA that is representative of cyanobacterial DNA. This DNA codes for some proteins also. Some mitochondrial DNA has been taken into the nuclear DNA where it's presence is rather obvious. And the mitochondria fission in reproducing themselves.
Where do some scientists think these bacteria originated?
Some scientists believe that these bacteria originated in hydrothermal vents deep in the ocean, where conditions are extreme and unique. The high temperatures, pressure, and chemical composition of these environments are thought to have provided a suitable habitat for the evolution of such bacteria.
What do scientist think mitochondria used to be?
Scientists believe that mitochondria were originally free-living bacteria that were engulfed by larger cells in a process called endosymbiosis. Over time, the relationship between the two evolved into a mutually beneficial symbiosis, with the mitochondria providing energy to the host cell in exchange for a protected environment.
What instrument has played a major role in permitting scientists to discover the chemical makeup of mitochondrion?
Microscopes have played a major role in permitting scientists to discover the chemical makeup of mitochondria. Using electron microscopes, scientists can study the ultrastructure of mitochondria and analyze their membranes and internal components at a molecular level. This has allowed for greater insights into the metabolic processes and functions of mitochondria in cells.
Two organelles that are believed to be remnants of unicellular bacteria are?
Mitochondria and chloroplasts are two organelles believed to be remnants of unicellular bacteria. Mitochondria are thought to have evolved from aerobic bacteria, while chloroplasts are believed to have originated from photosynthetic bacteria.
Where Might have Mitochondria originated from?
From early prokaryotes that lived symbiotically with eukaryotic cells Margules endosymbiont theory
