Which organelles are believed to have originated from free-standing bacteria ingested by ancient eukaryotic cells?

The endosymbiotic theory suggests that the mitochondria and chloroplast might have once been individual bacteria that were phagocotized by the host cell. This theory is backed up by the fact that mitochondria have different DNA from the host cell.

∙ 12y agoThe Mitochondria are thought to have originally been a unicellular entity that were consumed by a larger organism. Over time they would have adapted to function symbiotically with it's new host.
There are several reasons behind the belief, the main one being that the Mitochondria possesses it's own set of DNA, but instead follows the instructions of the cell it is contained within.

What are the eukaryotes bacteria?
Eukaryotic bacteria are bacteria that have a delineated nucleus and organ bound organelles. They are the "true" bacteria.
Some of the functions of the eukaryotic organelles are performed in bacteria by the?
Plasma Membrane
Are bacteria cells prokaryotic or eukaryotic and why?
Plant cells are Eukaryotic. Eukaryotic cells have a nuclei and membrane bound organelles. Prokaryotic cells are cells without a nuclei or membrane bound organelles. A bacteria cell is an example of a Prokaryotic cell. Plant and animal cell are examples for eukaryotic cells.
What is is the difference between prokaryotic and eukaryotic cells?
eukaryotic cells have a true nucleus and membrane-bound internal organelles. basically this means that eukaryotic cells organelles do not float around but have a specific spot in the cell. the organelles in a eukaryotic cell are each surrounded by a membrane isolating the organelle from the rest of the organelles. prokaryotic cells lack a true nucleus and do not have membrane-bound internal organelles. basically this means that prokaryotic cells have SOME organelles but the organelles that they do have float around. Most prokaryotes are single-celled organisms such as bacteria.
Are eukaryotic cells found in bacteria or located in cells cytoplasm or are multi celled organisms?
A Eukaryotic organism can be single celled or multi-celled. Eukaryote simply means that the cells themselves have organelles as opposed to prokaryotes like bacteria that do not have organelles.

Eukaryotic bacteria are bacteria that have a delineated nucleus and organ bound organelles. They are the "true" bacteria.
What is a word for bacteria?
Bacteria, by definition, is single-celled. Some bacteria, however, contains organelles and some doesn't. Bacteria without organelles is called prokaryotic, whereas bacteria with organelles is eukaryotic.
Some of the functions of the eukaryotic organelles are performed in bacteria by the?
Plasma Membrane
What are the two basic kinds of cells?
The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
Are plants animals and bacteria prokaryotes?
Plants, fungi and animals are eukaryotic. Bacteria are prokaryotic. Prokaryotes lack nuclear membranes and organelles.
Are bacteria cells prokaryotic or eukaryotic and why?
Plant cells are Eukaryotic. Eukaryotic cells have a nuclei and membrane bound organelles. Prokaryotic cells are cells without a nuclei or membrane bound organelles. A bacteria cell is an example of a Prokaryotic cell. Plant and animal cell are examples for eukaryotic cells.

What type of cell do animals have?
Plants and animals have eukaryoteic cells, these cells have membrane bound organelles and nuclei. Bacteria have prokaryoteic cells. These cells lack membrane bound organelles and no nuclei.
What are lysosmes?
Lysosomes are membrane bound organelles that are found in eukaryotic cells. They have acid hydrolase enzymes that digest excess or worn out organelles, food particles, engulfed viruses or bacteria.
Are insects eukaryote or prokaryote?
Insect cells are eukaryotic. Eukaryotic cells are defined by membrane bound organelles, the most prominent being the nucleus. Prokaryotic cells are defined by the lack of membrane bound organelles. The only organisms that are prokaryotic are bacteria and archebacteria.
Are plant cells prokaryotic?
Plant cells are Eukaryotic. Eukaryotic cells have a nuclei and membrane bound organelles. Prokaryotic cells are cells without a nuclei or membrane bound organelles. A bacteria cell is an example of a Prokaryotic cell. Plant and animal cell are examples for eukaryotic cells
