Why do scientists believe that mitochondria may have evolved from bacteria?

This theory is called the endosymbiotic theory. Mitochondria and chloroplasts both have their own ribosomes and their own genetic material, and they are also membrane-bound organelles. This is evidence that a long time ago, a prokaryotic cell incorporated another prokaryotic cell within itself, in its cytoplasm. This eventually came to create the first chloroplasts and mitochondria.

Wiki User
∙ 12y agoMitochondria and bacteria have many similarities: both have their own DNA, both have circular DNA, and both divide using similar methods.
Wiki User
∙ 13y agoOne very important piece of evidence is that these organelles have their own circular DNA from which they still transcribe house keeping proteins.
Wiki User
∙ 11y agoBecause they have their own DNA and replicate independently.They have 70s ribosomes.

∙ 11y agoBecause they have their own DNA.They have 70s ribosomes as bacteria.

Where do scientists believe plants evolved?
They believed plants evolved from prehistoric times.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
Mitochondria evolved from aerobic bacteria.Chloroplast evolved from photosynthetic bacteria.
Where might mitochondria have originated?
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
Do scientists believe plants evolved directly from cellulose?
No. Cellulose is a substance, not a living thing. Plants evolved from algae that developed cell walls made of cellulose.
How can you tell a mold from a bacteria on a petri dish?
The most important difference between molds, which are fungi, and bacteria is that fungi have a proper nucleus in their cells and bacteria do not.Fungi are known as eukaryotes because they have their DNA enclosed in a nucleus which separated from the cytoplasm by a nuclear membrane.Bacteria are known as prokaryotes because their DNA is not sepatated from the cytoplasm in a nucleus.In addition, fungi have other structures in their cells which bacteria do not have. For example, fungi have mitochondria, which are where food is 'burned' to release energy in the process of respiration.Bacteria do not have mitochondria. In fact, scientists believe that mitochondria actually evolved from ancient bacteria - theory called endosymbiosis.For descriptions of the different types of microbes, see:http://www.microbeworld.org/microbes/types.aspxFor differences between prokaryotes and eukaryotes see:http://www.earthlife.net/cells.HTMLFor an introduction to the endosymbiosis theory see:http://evolution.berkeley.edu/evolibrary/article/0_0_0/endosymbiosis_01
How do scientists think mitochondria originated?
Mitochondria are evolved from bacteria.Symbiotic living aerobic bacteria turned into mitochondria.
Does mitochondria have bacteria in it?
Mitochondria are evolved from bacteria.They do not contain bacteria.
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).
Where have mitochondria originated from?
They have evolved from bacteria. Aerobic bacteria have turned into them
Did mitochondria evolved from engulfed prokaryotes?
Yes,they were evolved from bacteria.They were aerobic bacteria.
The mitochondria of eukaryotes evolved from what type of organism?
Aerobic bacteria
How mitochondria or chloroplasts evolved?
Endosymbiotic theory describes the evolution of mitochondria and chloroplast.According to it,photosynthetic bacteria and aerobic bacteria engulfed by a eukaryotic cell turned into chloroplast and mitochondria.
What are mitochondria the descendants of?
She suggested that michondria and chloroplasts are descendents of prokaryotic endosymbionts.
Why might scientists believe that life evolved as bacteria around deep sea vents?
Perfect environment: dark, wet, warm to hot.
What organisms created the modern mitochondria?
Aerobic bacteria evolved into mitochondria.It is explained in endosymbiotic theory.
Where do we think mitochondria and chloroplasts came from?
They are thought to evolved from bacteria. Symbiotic living have turned them into organelles
Where do scientists believe plants evolved?
They believed plants evolved from prehistoric times.
