the host cell must provide protection that is shelter to the mitochondria form external harsh environmental conditions and must provide it the external precursors required to start the synthesis of its own ATP that is pyruvate in case of many eukaryotic cells.

Do mitochondria make their own food?
Not really. Mitochondria use their DNA to produce many proteins and enzymes required for their function but not all. That makes the idea that they make their own food a little fuzzy. They can't live outside the cell that they are in, since they need some things from the 'host' cell.
Could an organism survive without its mitochondria if all the other organelles were present?
Primordial bacteria have no organelles. They represent the stage of evolution before organelles were acquired. Organelles (probably) began as infectious bacteria invading ameoba-like cells. If the host didn't kill them off and they didn't kill the host then the bacteria become a sort of parasitic organelle. These can be removed without too much harm to the host. In fact the host would probably benefit by their removal. If the parasitic bacteria them started to provide some service to the host cell then the host benefits from their presence. If the service they provide duplicates some basic process of the host then the host will 'forget' how to do the service itself and rely solely on its (now) symbiotic organelles. This is a very common facet of living things: if you don't use a certain ability then you lose it. Removal of the organelles at this stage would be fatal to the host.
What is Mitochondria are descendants of?
Mitochondria are thought to be descendants of ancient free-living bacteria that were engulfed by a host cell through endosymbiosis. Over time, the host and the endosymbiont developed a symbiotic relationship, with the host providing protection and nutrients while the endosymbiont provided energy in the form of ATP through aerobic respiration. This symbiosis eventually led to the evolution of eukaryotic cells, including our own.
Is a mitochondria living or nonliving?
There is no yes or no answer to this question, it is the same with the question on whether or not viruses are alive. It is worth mentioning though, that mitochondria are able to respire unlike viruses. They share a few characteristics with living organisms. Mitochondria poses their own DNA, they reproduce and respire. Mitochondria are similar to bacteria in many ways. A good theory on the origin of mitochondria is that a bacteria survived after being engulfed by a larger cell, and formed a mutual symbiosis. If it helps, my personal opinion is that mitochondria are alive, but heavily dependent on a mutual symbiosis of a host cell.
Why mitochondria culture is not possible?
Chloroplasts cannot live on their own. They must have the cell they live in to survive. The theory is that endosymbiosis occurred millions of years ago, and the chloroplasts lost much of their self functioning genes to the host cell, depending instead on the cell to maintain life. They have become so specialized at their job within the cell, they are no longer able to support their own lives outside of it.

Why a mitochondria are considered a antique bacteria?
It has its own DNA completely separate from the DNA of the host cell.
Does food or other digested material have an effect on mitochondria and DNA?
Almost all eukaryotic organism have two types of Genetic material. Genomic DNA and mitochondrial DNA. Mitochondria itself a seperate bacteria, in evolution they are engulfed by the host cell. Mitochondria provides(synthesis) the energy needed by host cell. In turn, the host cell protects the mitochondria from the environmental hazards. The relationship is symbiotic in nature. If we ate food or antibiotics which affects the bacteria, there is a chance that will affects the mictochondrial DNA too.

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.
Is mitchondria a plant cell or animal cell?
It's neither. It's an organelle that can be found within both plant and animal cells. Mitochondria do seem to resemble some prokaryotic cells and it is thought that the evolutionary origin of mitochondria is a rather extreme form of symbiosis where free living bacteria and their host cells gradually became so interdependent that the bacteria ultimately became an organelle within the host cell.
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.
Does the way the mitochondria look affect the way it works?
Not really, but all the "roughness" of its membrane allows the speed of reaction with the host cell to speed up.

How do viruses and bacteria differ?
The 5 Kingdoms in biology provide categories for all living things. They are:PlantsAnimalsBacteriaFungiProkaryotesViruses have to have a host cell (or an 'invaded' cell) to survive, so scientists don't class them as a living organism.Viruses are different from all bacteria.
