I would say that we have 3 subjects here. (03)
There is the cell in reality. There are what are called biological models of
a cell that have been developed as part of that science and there is now an
attempt an ontological "model" of the cell. (04)
Of course, to be any good we should leverage the biological model to guide us
in what the "coherent, controlled vocabulary" (and constraints) of the
ontological model will express. So we are not trying to build a cell model from
scrathc but we are using a model and adapting it to ontological purposes. In
the process we may simplify the biological model to reflect expressivity
constraints etc. So in the end we may indeed have a model, but at this stage
of ontological engineering probably not as good as the biological one. Of
course in the process of formalizing things we may discover some inaccuracies
in the way the biological model expressed some things. (05)

But when one is building an ontology for, e.g., cell biology, is one
trying to build a model of the cell, or rather to create a formally
coherent controlled vocabulary for talking about cells and their parts?
