New changes to plant anatomy ontology

[Katica Ilic]

Hello,

Here is the list of changes that I made to the plant anatomy ontology
yesterday. I have not committed it yet, and if everyone agrees, I would
like to commit the new files to the cvs as soon as possible.

I've corrected all the mistakes in my cell type node that ocurred after
this node got imported to the main ontology (due to the parantage of the
terms that already existed in the anatomy ontology).

1. Merged  the existing PO term sperm nuclei (PO:0020098) to the
cell type term sperm cell (PO:0000084). This seems better idea than
deleting the term sperm nuclei (when I did this, it didn't show up in
the obsolete node). First, sperm cells are indeed whole cells, not just
nuclei, and second, we agreed not to have subcellular structures in the
anatomy ontology.

2. Changed Felipe's term antipodals to antipodal cell (to avoid
plurals).

3.Deleted embryo sac from the cell type node; this term is still
present in the gametophyte node.

4. Couldn't do the same with pollen under the microspore term, that ended
up there as I explained in the earlier message (when I did, all the
instances of pollen were gone with all the childrens). So I had to make
term pollen a synonym of the male gametophyte. This way, pollen was gone
from my cell type node, and male gametophyte is still present as a child
of the gametophyte. (I should do the same with embryo sac and female
gametophyte at later times).

Please let me know if you have objections to any of the changes
described above.

Greetings,

Katica
