Dear Barry,

The definitions we have for  Is a = [i] is:

It is used to describe the relationship between a child term that 
represents a specific type of a more general parent term.
For example  a guard cell is a type of cell; a root hair is a cell.


Since this is a plant structure ontology (dedicated) we did not name the 
term 'plant cell', as you would have expected had it been a cell type 
ontology. Also the definition communicates that we are talking about the 
plant cell. definition: 'Structural and physiological unit of a living 
organism; it (i.e., plant cell) consists of protoplast and cell wall; in 
nonliving state, of cell wall only, or cell wall and some nonliving 
inclusions.'

All the children we have for the parent term 'cell (PO:0009002)' are
subtypes of plant cells. Thus no question of having non-plant cell types 
in this ontology or as children.
