"The mitochondrion and the chloroplast both have a number of unusual features that distinguish them from other organelles: they contain their own DNA that loops around like that of bacteria, they manufacture many of their own proteins, and they both reproduce by binary fission. This is very similar to what bacteria do. The similarity has led many scientists to conclude that these organelles may have evolved from independent bacteria that took up residence in early eukaryotic cells billions of years ago. These bacteria eventually became so dependent on their hosts, and vice versa, that they have essentially become one organism" (Beyond Books, Apex Learning Inc.)

What else can I help you with?
Chloroplasts are to plants as what are to aerobic respiration?
Mitochondria are to aerobic respiration. Mitochondria are responsible for producing ATP through cellular respiration in eukaryotic cells, similar to how chloroplasts are responsible for photosynthesis in plant cells.
Who has mitochondria and chloroplast cells?
They are in plant cells mostly.Also some protists have
Why do scientists believe that mitochondria were separate organisms?
There are several reasons. First, mitochondria have a capsule around them very similar to bacterial capsules. Second, mitochondria are the only organelles in animal cells with their own genetic material. Third, mitochondria replicate themselves. Fourth, mitochondria are genetically similar to some bacteria.
How does fungi survive without a chloroplast?
Animal cells doesn't need any Chloroplast to live because all the nutritions, Protins,Oxygen and other substance are carried by blood.So, Like plant cells animal cell don't need any chloroplast to survive
Are mitochondria associated with bacterial cells?
No, mitochondria are only present in eukaryotic cells. Bacteria are prokaryotic cells.
Which organelle indicates that eukaryotic cells have evolved from prokaryotic cells?
Mitochondria, which are thought to have originated from a symbiotic relationship between early eukaryotic cells and aerobic bacteria, provide evidence that eukaryotic cells have evolved from prokaryotic cells. Mitochondria have their own DNA and ribosomes, similar to prokaryotic cells, and carry out cellular respiration, a process that is also similar to bacterial metabolism.
Chloroplasts are to plants as what are to aerobic respiration?
Mitochondria are to aerobic respiration. Mitochondria are responsible for producing ATP through cellular respiration in eukaryotic cells, similar to how chloroplasts are responsible for photosynthesis in plant cells.
Shape of mitochondria and chloroplast?
The mitochondria and chloroplast are both complex cell organelles that are found in eukaryote cells. These are both oval in shape.
Why do plant cell have chloroplast and animals do not?
Plants cells have chloroplasts because they need it for a process called photosynthesis. But both plant and animal cells have mitochondria. Animal cells can use the mitochondria to get energy that why they need chloroplast.
What were the characteristic of mitocondria and chloroplast that caused scientists to hypothosize that they were originaly prokaryotic cells that were engulfed by early eukaryotic cells?
Following characteristics of mitochondria and chloroplast led Margulis (1983) and other scientists to hypothesized that mitochondria and chloroplast were Bacteria and Cyanobacteria that were engulfed by Amoeboid Eucaryotic cells and became symbiotic organelles. 1; Both mitochondria and chloroplast (M&C) are self replicating. 2; Both possess small circular DNA molecule similar to Plasmids. 3; Both possess an outer membrane similar to eukaryotic cell membrane. 4; Both possess an inner membrane simillar to prokaryotic cell membrane as it lacks sterols. 5; Both possess ribosome similar to prokaryotes and smaller than eukaryotic ribosomes. 6; Both produce their own m RNA and some proteins . 7; Both can produce their own ATP. 8; Both are semidependent on animal or plant cell. this hypothesis is called Endosymbiont hypothesis,

What is the purpose of the chloroplast in bacteria cells?
Bacteria do not have chloroplasts.Only eukariyotes have them.
What three organic polymers are found in cells?
nucleus, mitochondria and chloroplast
How are chloroplasts and mitochondria similar to bacteria?
Chloroplasts and mitochondria have their own DNA and ribosomes, similar to bacteria. They also reproduce independently within the cell through a process resembling binary fission, just like bacteria. Additionally, both organelles are thought to have originated from endosymbiotic relationships with ancient bacterial cells.
Are mitochondria associated with bacterial cells?
No, mitochondria are only present in eukaryotic cells. Bacteria are prokaryotic cells.
How does fungi survive without a chloroplast?
