Mitochondria were evolved from bacteria.This is explained by endosymbiotic theory.

∙ 10y ago
Mitochondria are thought to have originated from a symbiotic relationship between a primitive eukaryotic cell and an ancient aerobic prokaryote. This endosymbiotic event led to the development of a mutually beneficial relationship where the prokaryote provided energy through aerobic respiration, and the eukaryotic cell provided protection and nutrients. This eventually led to the evolution of complex eukaryotic cells with mitochondria as specialized organelles for energy production.

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.
What contribution did an ancestral aerobic bacterial cell make to eukaryotes?
Mitochondria and chloroplasts for two contributions here through endosymbiosis.
Mitochondria and plastids likely formed in eukaryotes in what way?
Mitochondria likely formed through endosymbiosis with an aerobic bacterium, while plastids likely formed through endosymbiosis with a photosynthetic cyanobacterium. Both organelles have their own DNA and replicate independently within eukaryotic cells.
Which organelle is believed to have been a symbiont of an ancient cell?
Mitochondria are believed to have originated as symbiotic bacteria that were engulfed by ancestral eukaryotic cells. This theory is known as endosymbiosis and is supported by evidence such as the mitochondria having their own DNA and ribosomes.
Is mitochondria a virus?
No, mitochondria are not viruses. Mitochondria are organelles found in eukaryotic cells that play a key role in generating energy for the cell through a process called cellular respiration. They are believed to have originated from bacterial cells that were engulfed by primitive eukaryotic cells through a process known as endosymbiosis.
What is the generally accepted evolutionary process which created the organelles and chloroplasts and mitochondria?
The generally accepted concept is endosymbiotic theory, which suggests that mitochondria and chloroplasts were once free-living prokaryotic organisms that were engulfed by ancestral eukaryotic cells. Over time, these prokaryotic organisms formed a symbiotic relationship with the host cell, leading to their integration as organelles within eukaryotic cells. This process allowed for the specialization and evolution of these organelles to carry out specific functions within the cell.
Eukaryotic cells acquired mitochondria and chloroplasts by?
engulfing prokaryotic cells through a process called endosymbiosis. Over time, these prokaryotic cells formed a mutualistic relationship with the host cell, eventually evolving into the mitochondria and chloroplasts found in eukaryotic cells today.
How did the eukaryote evolve?
Eukaryotes evolved from a process call endosymbiosis. Endosymbiosis states that eukaryotes started as two separate bacterium. The bigger bacteria engulfed the smaller. This is how the mitochondria is enclosed in the cell. There is evidence of this because the mitochondria has its on cell membrane and contains its own DNA.
Why do Biologists suspect endosymbiosis gave rise to mitochondria before plastids?
Biologists suspect that mitochondria arose before plastids through endosymbiosis because mitochondria are present in almost all eukaryotic cells, while plastids are only found in photosynthetic eukaryotes. Additionally, mitochondria share more structural and functional similarities with their bacterial ancestors than plastids do.
What it call when the mitochondria in cells today are the descendants of aerobic prokaryotes that used oxygen to generate energy?
This phenomenon is known as endosymbiosis, specifically referring to the theory that mitochondria and chloroplasts originated from free-living aerobic prokaryotes that were engulfed by ancestral eukaryotic cells and established a symbiotic relationship.

Mitochondria likely formed through endosymbiosis with an aerobic bacterium, while plastids likely formed through endosymbiosis with a photosynthetic cyanobacterium. Both organelles have their own DNA and replicate independently within eukaryotic cells.
What is endosymbiosis?
Endosymbiosis is a process in which one organism lives inside another and they form a mutually beneficial relationship. This concept is often used to explain the origins of organelles such as mitochondria and chloroplasts in eukaryotic cells.
What does the endosymbiosis theory propose?
The endosymbiosis theory proposes that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms. It suggests that organelles such as mitochondria and chloroplasts were once independent prokaryotes that were engulfed by a host cell, eventually forming a mutually beneficial relationship.
What is the endosymbiotic theory?
The Endosymbiotic Theory is a theory about how mitochondria and chloroplasts formed. The theory suggests that both the mitochondria and chloroplasts were once prokaryotic cells that were ingested but not digested by eukaryotic cells. This would explain why both have their own DNA.
What enabled the formation of true living cells?
Endosymbiosis enabled the formation of true living cells. This concept explains the origin of two biological structures, the mitochondria and the chloroplasts.
