There is a theory that chloroplasts and mitochondrias were once a free living bacteria that came inside a eukaryotic cell and started a mutual relationship with the eukaryotic cell. The bacteria got to have a shelter, and in return, the eukaryotic is able to create more energy by mitochondrias, or be able to convert from co2 to o2. It is only a theory though.

∙ 14y agoMitochondria and chloroplasts both contain their own DNA and are capable of producing some of their own proteins. This suggests that both of these organelles were originally separate micro-organisms, but have become part of eukaryotic cells through symbiosis, and evolution has ensured that they are now vital for cell life due to the many advantages of compartmentalisation over an organelle free structure.

∙ 14y agoBoth the mitochondria and chloroplast are believed to have prokaryotic origins. They are commonly believed to once have been bacteria that were engulfed by eukaryotic cells where they lived together with a mutualistic relationship. They would supply the eukaryotic cell with energy and the eukaryotic cell would provide them with protection. Both the mitochondria and chloroplast have their own separate genome unique to the DNA of the cell they are contained in which supports this theory or endosymbiotic evolution.

∙ 9y agoChloroplasts of eukaryotic cells are thought to be originated by engulfing cyanobacteria. The endosymbiotic theory could explain the evolution of cell organelles chlorplast, mitochondria from the bacteria (symbiosis). Please refer the following detail and reviews for more knowledge:

What organelle in a plant makes glucose come from sunlight?
The chloroplasts...I think...
Two organelles that are believed to be remnants of unicellular bacteria are?
The chloroplasts and mitochondria in plants and the mitochondria in animals.
Why does thylakoid membranes of chloroplasts resemble those of cyanobacteria?
Thylakoid membranes of chloroplasts resemble those of cyanobacteria because chloroplasts are believed to have evolved from endosymbiotic cyanobacteria. During evolution, the cyanobacteria that were engulfed by a host cell eventually became mutually beneficial, leading to the development of chloroplasts. The structural similarity between the thylakoid membranes of chloroplasts and cyanobacteria is a remnant of this evolutionary relationship.
What is a characteristic of chloroplasts that suggests that they might have evolved from free-living bacteria?
Photosynethic bacteria are likely involved.
Where does the main thing that causes the green color of plants come from?
Chlorophyll make plants green.They are in chloroplasts.
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.
Two organelles that are believed to be descendants of unicellular bacteria are?
mitochondria and chloroplasts
What organelle in a plant makes glucose come from sunlight?
The chloroplasts...I think...
Two organelles that are believed to be remnants of unicellular bacteria are?
The chloroplasts and mitochondria in plants and the mitochondria in animals.
What cells do chloroplasts come from?
plant cells contain chloroplasts. They make the plant look green and are where photosynthesis takes place.
Where does the energy come from that chloroplasts use to make food?
Sunlight.

Is chloroplast found in all cellls or just come?
chloroplasts are in photosynthetic organisms.But they are not in prokariyotes.
What contains its own DNA and is believed to have come from the incorporation of prokaryotic cell into a eukaryotic cell millions of years ago?
The mitochondria contains it's own circular DNA that still codes for some proteins.The chloroplasts of plant also contain circular coding DNA.
Where does the chloroplasts come from?
They are thought to be evolved from bacteria. They have 70s ribosomes ,circular DNA like bacteria
Where does the main thing that causes the green color of plants come from?
Chlorophyll make plants green.They are in chloroplasts.
