Thank you for adding some clarity. Still, two questions still seem unanswered. First, wouldn't culturing of an animal cell be sufficient to demonstrate that the cell is "an individual form of life"?
Second, the good Primate refers to a "human life". I know what is human (e.g. human hepatocyte) and I know what is alive (e.g. human hepatocyte). But somehow the Primate doesn't seem to think, e.g., that a hepatocyte is a human life. It's rather like thinking that a car that is red is not a red car.
Notice, a hepatocyte is diploid. So it isn't clear to me why you made the diploid/haploid distinction when defining "organism".
