a mitochondrion (plural mitochondria) (from Greek μιτος or mitos, thread + κουδριον or khondrion, granule) is an organelle, variants of which are found in most eukaryotic cells.[1] Mitochondria are sometimes described as "cellular power plants," because they convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation. Usually a cell has hundreds or thousands of mitochondria, which can occupy up to 25% of the cell's cytoplasm. Mitochondria have their own DNA and may, according to the endosymbiotic theory, be descended from free-living prokaryotes that were closely related to rickettsia bacteria
What else can I help you with?
Where did mitochondria originate from?
Mitochondria are believed to have originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. This symbiotic relationship eventually led to the evolution of mitochondria as specialized organelles within eukaryotic cells.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What are the energy-producing organelles?
The energy-producing organelles in cells are called mitochondria. They generate ATP (adenosine triphosphate), which is the energy currency of the cell, through a process called cellular respiration. Mitochondria contain their own DNA and are thought to have originated from symbiotic bacteria.
What two organelles are derived from symbiotic bacteria?
Chloroplasts and mitochondria. It is believed they were engulfed by the cells because of the dual membrane present on both. Both are believed to have originated from an endosymbiotic bacteria. Mitochondria's inner matrices contain DNA, and they have many features similar to those of bacteria. Chloroplasts are believed to have come from an endosymbiotic cyanobacteria.
Why does mitochondria have a double membrane structure?
Mitochondria have a double membrane structure because they are believed to have originated from a process called endosymbiosis, where a smaller prokaryotic cell was engulfed by a larger cell. The double membrane allows for compartmentalization of different functions within the mitochondria, such as the production of energy through cellular respiration.
Where Might have Mitochondria originated from?
From early prokaryotes that lived symbiotically with eukaryotic cells Margules endosymbiont theory
Where have mitochondria originated from?
They have evolved from bacteria. Aerobic bacteria have turned into them
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
How do scientists think mitochondria originated?
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 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.
Where did mitochondria originate from?
Mitochondria are believed to have originated from ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. This symbiotic relationship eventually led to the evolution of mitochondria as specialized organelles within eukaryotic cells.
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.
Which of these cellular organelles have their own DNA?
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
How are mitochondria and chloroplasts manufactured in the cell?
Both of them are thought to have originated from primitive bacteria. This theory is called Endosymbiont theory.
