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.
Scientists believe that mitochondria may have evolved from bacteria because they have their own DNA, replicate independently within cells, and have similar characteristics to certain types of bacteria. Additionally, the endosymbiotic theory suggests that mitochondria were once free-living bacteria that were engulfed by early eukaryotic cells and formed a symbiotic relationship.
Mitochondria and bacteria have many similarities: both have their own DNA, both have circular DNA, and both divide using similar methods.
One very important piece of evidence is that these organelles have their own circular DNA from which they still transcribe house keeping proteins.
Because they have their own DNA and replicate independently.They have 70s ribosomes.
Havin 70s ribosomes in all three.Self replicating ability and having circular DNA.
Because they have their own DNA.They have 70s ribosomes as 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 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 have mitochondria and chloroplasts have evolved?
Mitochondria and chloroplasts are thought to have evolved from ancient symbiotic bacteria that were engulfed by early eukaryotic cells. Over time, these bacteria formed a symbiotic relationship with the host cells, with the bacteria providing energy (mitochondria) or photosynthesis capabilities (chloroplasts) in exchange for protection and nutrients. This symbiosis eventually became permanent, leading to the development of these organelles within eukaryotic cells.
Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
What two organelles are derived from symbiotic bacteria?
The mitochondria and chloroplasts are organelles derived from symbiotic bacteria. Mitochondria are thought to have originated from a bacterial ancestor that was engulfed by a primitive eukaryotic cell, while chloroplasts are believed to have evolved from cyanobacteria through a similar process of endosymbiosis.
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.
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
What do scientist think mitochondria used to be?

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 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.
Did mitochondria evolved from engulfed prokaryotes?
Yes, mitochondria are believed to have evolved from engulfed aerobic bacteria that formed a symbiotic relationship with early eukaryotic cells. This theory is known as the endosymbiotic theory and is supported by similarities between mitochondria and modern-day bacteria, such as their own DNA and ability to replicate independently.
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 are mitochondria the descendants of?
Mitochondria are thought to be descendants of ancient bacteria that were engulfed by early eukaryotic cells through a process called endosymbiosis. Over time, this symbiotic relationship evolved into the mitochondria we see in cells today.
Why might scientists believe that life evolved as bacteria around deep sea vents?
Perfect environment: dark, wet, warm to hot.
