Both mitochondria and choloplasts were thought to be single-celled bacteria that got "eaten" by other organisms, eventually giving rise to complex organisms that have mitochondria or chloroplasts in their cells (see endosymbiotic theory). Consequently, both mitochondria and chloroplasts are very similar to bacteria. One of the similarities is that both have their own DNA and replicate independently of the rest of the cell.

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 principal organelles of eukaryotes that share features with one another and with bacteria from which they apparently were derived are the?
Two principal organelles of eukaryotes that share features with one another and with bacteria are the mitochondria and chloroplasts. Both organelles have their own DNA and ribosomes, similar to bacteria, and are thought to have originated from ancient endosymbiotic bacteria that were engulfed by early eukaryotic cells.
The stongest evidence for the endosymbiotic origin of eukaryotic orgelles is the homology between extant prokaryotes and?
...eukaryotic organelles, such as mitochondria and chloroplasts. These organelles have their own DNA, ribosomes, and are similar in size to prokaryotes like bacteria. Additionally, the double membrane structures of mitochondria and chloroplasts resemble what is seen in prokaryotic cells.
Two organelles that are believed to be descendants of unicellular bacteria are?
Two organelles that are believed to be descendants of unicellular bacteria are mitochondria and chloroplasts. The endosymbiotic theory suggests that these organelles were once free-living bacteria that were engulfed by ancestral eukaryotic cells and formed a symbiotic relationship.
What are 3 pieces of scientific evidence that supports the endosymbiotic theory?
The presence of double-membrane structures in mitochondria and chloroplasts similar to bacterial cells supports the theory of endosymbiosis. The existence of circular DNA in mitochondria and chloroplasts, similar to bacterial DNA, provides evidence of their bacterial origin. Phylogenetic studies reveal that the genetic material in mitochondria and chloroplasts is more closely related to certain groups of bacteria than to eukaryotic nuclear DNA, supporting their evolutionary history as once-independent organisms.

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.
How are mitchondria and chloroplasts similar?
Mitochondria and chloroplast are botn thought to be what remains of ancient bacteria. They are both about the size of a bacteria and both of them contain their own DNA. Mitochondria is responsible for cellular respiration using the sugar generated in the chloroplasts.
Two principal organelles of eukaryotes that share features with one another and with bacteria from which they apparently were derived are the?
Two principal organelles of eukaryotes that share features with one another and with bacteria are the mitochondria and chloroplasts. Both organelles have their own DNA and ribosomes, similar to bacteria, and are thought to have originated from ancient endosymbiotic bacteria that were engulfed by early eukaryotic cells.
Do mitochondria and chloroplasts contain ribosomes?
Yes.They have 70s ribosomes. They are similar to 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.
How are mitochondria and chloroplasts similar?
mitochondria and chloroplast are similar as chloroplast and mitochondria both are power houses of cell.chloroplast prepares food and mitochondria releases oxygen as both are providing power they are similar
What organelle have the same function as an mitochondria?
Chloroplasts have a similar function.

Which of these cellular organelles have their own DNA?
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
Is mitochondria and chloroplasts endosymbiotic?
Yes, both mitochondria and chloroplasts are considered to be endosymbiotic organelles because they are believed to have evolved from free-living bacteria that were engulfed by ancestral eukaryotic cells. This symbiotic relationship enabled the host cell to obtain energy more efficiently through aerobic respiration (mitochondria) and photosynthesis (chloroplasts).
