1.) Mitochondria and plastids are relatively the same size as bacteria
2.) Mitochondria and plastids have nucleiod DNA molecules - just like bacteria.
3.) Mitochondria and plastids reproduce the same way as bacteria - binary fission.
The ribosomes of chloroplasts are more similar in structure to ribosomes found in prokaryotes than to ribosomes found in eukaryotes.
Another answer:
Both chloroplasts and mitochondria have their own DNA and it is not the same as that in the nucleus of the cell.
The strongest piece of evidence for the endosymbiotic theory is the fact that mitochondria and chloroplasts have their own circular DNA, prokaryote fashion, and can still replicate, transcribe and translate some proteins. Their ribosomes are also fashioned as a prokaryotes would be.
The theory of endosymbiosis states that eukaryotic cells evolved when some prokaryotes were engulfed by others and avoided being digested. The theory states that chloroplasts developed from photosynthetic bacteria and mitochondria from aerobic bacteria.
Evidence in support of the endosymbiotic theory includes:
1) The inner membranes of chloroplasts and mitochondria have enzymes and transport systems similar to those found in bacteria
2) They reproduce themselves by splitting into two, similar to the process of binary fission in bacteria
3) They contain circular DNA molecules which are not combined with proteins, like bacteria and unlike the eukaryotic DNA in the nucleus
4) They have their own ribosomes, which are more like bacterial ribosomes than eukaryotic ones.
There are two examples in Biology. Mitochondria found in animals, plants and fungi have their own DNA and they divide on their own. They don't necessarily divide when the cell divides but more of them are needed for the cell. Chloroplasts found in plants also have their own DNA. It is thought that both organelles are symbiotic.
one is 2 cell membranes but I'm not sure of the others.
The endosyymbiotic theory stated that the mitochondria formed through the endosymbiosis of a proteobacteria. It also states that chloroplast formed from the endosymbiosis of a cyanobacteria.
Precense of 70s ribosomes in .Chloroplast and mitochondria.Precense of circular DNA and own mechanisms for protein synthesis in chloroplast and mitochondria.
Chloroplasts and Mitochondria have 70s ribosomes,same as bacteria. They have their own DNA. They can produce proteins themselves.
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
Evidence
Evidence supports a model in which periods of relative stability are punctuated by short periods of rapid (relatively speaking) change. It could, theoretically, be possible for evolution to proceed in a gradual manner. However, mathematical modelling and fossil evidence show that punctuated equilibrium is the norm.
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.

Molecular Genetics
Law and math prove things. Science supports tentative ( more or less ) explanations of natural phenomenon with evidence. The evidence overwhelmingly supports evolutionary theory. PS Evolution itself is a observed and observable fact.
Theory of evolution
"Evidence". There's no special term to distinguish evidence supporting one theory in science from evidence supporting any other theory in science.
The evidence that supports wegeners hypothesis is the fossil evidence

vestgial structures fossils embryology also a big one is that there is a universal genetic code
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.
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
Technically speaking, evolution isn't a fact; a fact is an "observable and verifiable observation", in contrast to a theory or hypothesis which explains a group of such facts. In contrast, evolution happening can be considered a fact by this defintionAlso, as defined in common usage it can be considered a fact, based on the support and evidence it has:Fossil evidence supports it.DNA evidence supports it.The comparison of similar species and structures ("analogous structures")("comparative anatomy") shows it is possible.Comparison of geographical distribution shows it is possible.Comparison of similar biochemistry and physiology supports it.Applied studies of "complex iteration" (mathematical models of how natural selection and random development occur) show it is possible, and support it.Evidence of observed speciation supports it.
