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.
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).
Do mitochondria and choloroplast independently?
Mitochondria and chloroplasts are thought to have evolved independently. While they share some similarities, such as their own DNA and ability to generate energy in the form of ATP, their origin and function differ. Mitochondria likely originated from ancient bacteria that were engulfed by primitive eukaryotic cells, while chloroplasts are believed to have evolved from photosynthetic cyanobacteria that were also engulfed by eukaryotic cells.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
Which is used as evidence for the idea that the domain Eukarya evolved from unicellular organisms?
Mitochondria and chloroplasts have their own DNA.

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 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.
Why do animal cells not have chloraplast?
Chloroplasts (as well as Mitochondria) are endosymbionts. This means that they are cells, living within another cell. Historically, eukaryotic cells had no mitochondria or chloroplasts (and mitochondria and chloroplasts existed by themselves outside of cells). The current hypothesis is that a cell tried to engulf a mitochondria (by phagocytosis) but failed in digesting it. Over time, some of the mitochondrial DNA (mtDNA) became part of the host cell's genome. This cell is a common ancestor to both plants and animals, which is why both have mitochondria. A cell with mitochondria then did the same thing with chloroplasts, absorbing one, and taking some of its ctDNA etc. Because not all cells that had mitochondria absorbed chloroplasts there were cells with mitochondria only, and cells with mitochondria and chloroplasts. The ones with chloroplasts evolved to become plant cells, and those without evolved to become animal cells.
Where do we think mitochondria and chloroplasts came from?
They are thought to evolved from bacteria. Symbiotic living have turned them into organelles
Is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA.

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.
What organelle is responsible for converting food into energy?
Mitochondria and Chloroplasts are involved in energy conversion.
Do mitochondria and choloroplast independently?

While they share some similarities, such as their own DNA and ability to generate energy in the form of ATP, their origin and function differ. Mitochondria likely originated from ancient bacteria that were engulfed by primitive eukaryotic cells, while chloroplasts are believed to have evolved from photosynthetic cyanobacteria that were also engulfed by eukaryotic cells.
