Now it comes to "resurrection." this would be like , eventually, making people come back to life - in what state i don't know - and fruit pips being grafted back into the full fruit, for full consumption. the fundamental theory here is that mass is stored energy, of course.
So, if you have the bones of people, they carry all the genes the person had up until the time they died. this means that you can reproduce the physical form of the person and memories to some degree, or fully with more research by doctors, and then the exact impulses that they had will come back to the body due to the energies the body had at the time of death. the thing is, the person might come back having seen heaven or something, of course, and then have a great story to tell, yes?
If we were to take the decomposing bones, or, even a photograph, we could simulate this with some certainty that each wrinkle on the outside of the face, and, every scar on the body needs to be identical to an atomic level for the person to be brought back "exactly as they were" before they died. this is because our bodies are merely nerves, that make a complexion for us that represents what is going on inside our bodies, of course.
Of course if we have the bones, the actual d.n.a, then we could merely reproduce this, at least in a test tube, regenerating the physical form of the person. this would result in, for lack of a better example, something like the water cycle, or, 'the circle of life.'
~ Remember that the body of the person is only a 'collection of nerves.' when nerves feel things, they change for each thing they feel, permanently. this forms the person, there is no hocus pocus consciousness and memories that are stored like photographs. they are merely impressions of the persons experiences.
If you have the ashes of someone, then you could simply 'revitalize them.' this would be where you revert the ashes to cells, by taking the blue print of the genes, as if it were a forest fire leaving behind a mountain with fissures and details of ground, by lubricating them to 'revitalize them.' this follows the forest fire cycle of course, except we are taking the ashes and rewinding them.
For the vegetables and fruit, we merely need to take the genes of the fruit, from a little bit of it, then 'copy' this code to file, then replicate it.
