One hypothesis is that mitochondria are "swallowed" bacteria that were not digested but instead incorporated into the cell as a symbiont (helper). Mitochondria have a membrane similar to the cell membrane and their own genetic material similar to bacteria.

What features do all animals and plants cells have in common?
Because way in the past they are descended form a common ancestor.
What organism is the mitochondria in?
first mitochondria is an organism second a mitochondria can be in an animal cell
Is the mitochondria studded with ribosomes?
Mitochondria contains ribosomes in them.Those are produced by mitochondria.
Which of these cellular organelles have their own DNA?
Two of the cellular organelles that have their own DNA are chloroplast and a nucleus. The mitochondrion also have there own DNA.

Why are mitochondria found in both animal and plant cell?
because their last common ancestor (way back in precambrian) had mitochondria.
What features do all animals and plants cells have in common?
Because way in the past they are descended form a common ancestor.
Which do chloroplasts and mitochondria have that other organelles lack?
There is a theory that chloroplast and mitochondria were independent organisms. Since they were, they would have their own DNA. And it is true that they do. It is interesting that you get your mitochondria from only your mother. There are many studies have used mtDNA to trace the evolution and migration of human species, including when the common ancestor to modern humans and Neanderthals lived.
Why are mollusks classified as animals?
Because they are - they eat and move and breathe and are made of animal cells (nucleus, mitochondria, no chloroplasts). They evolved from the common ancestor of animals. They are animals in everything.
The sequence of amino acids in the cytochrome c molecule an enzyme found in mitochondria is identical in humans and chimpanzees This fact best supports the concept that?
human and chimpanzees have a common ancestor
What types of cell are mitochondria found?
Eukaryotic cells have mitochondria (singular mitochondrion).
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.
What is a relative who was born long ago called?
An ancestor.
What is the organelle where respiration occurs?
Cellular respiration occurs in the mitochondria.
What is the evolutionary ancestor ancestor to the fungi?
Scientists have not identified an evolutionary ancestor to fungi.
Which cellular organelle uses oxygen and glucose to provide energy?
The mitochondria.
What is a synonym of mitochondria?
mitochondria
