#503 new cell types part_of pith, hypocotyl & tapetum


Need new terms for following cell types
-tapetum/tapetal cell (http://www.ncbi.nlm.nih.gov/pubmed/21515697)
-hypocotyl cell (http://www.plantcell.org/content/10/10/1623.abstract)
-pith cell/pith parenchyma cell (http://www.pnas.org/content/107/51/22338.full.pdf)
--root pith cell (-->part_of PO:0005040 : root pith)
--shoot axis pith cell (-->part_of PO:0005041 : shoot axis pith )

There are some

    Given that most cells that are part of one of these structures are already classified as another cell type (e.g., parenchyma cell, epidermal cell, etc.), I suggest creating these categories using only intersection_of relations.

    For example:
    pith cell = intersection_of is_a plant cell / intersection_of part_of pith

    Might work, but this doesn't tell me whether it is a parenchymatous or some other type

    You would know whether it is parenchymatous or whatever based on the primary classification.

    Of course, in some of these cases, you might only have one cell type. For example, pith is a portion of parenchyma, so any cell that is part of it would be a parenchyma cell. In that case, you are better off just making a subclass of parnechyma cell called pith parenchyma cell and there is not need to make a general class called "pith cell".

    The cross products are more important for structures that have different kinds of cells as part. For example, if you wanted to make a class called "petal cell", which was defined as a cell that is part of a petal, you should define that class using cross products (analogous to our class "floral organ").
