Chris,

Do you want us to add the cell terms in PO as Xrefs.

xref_analog: CL:ID
e.g
xref_analog: CL:0000540


[Term]
id: PO:0000293
name: guard cell
namespace: plant_structure
def: "One of a pair of cells flanking the stomatal pore." [ISBN:0471245208]
comment: They cause the opening and closing of the pore by changes in 
turgor.
xref_analog: CL:0000292--->CHECK THIS FOR SUGGESTED ADDITION
is_a: PO:0004013 ! epidermal cell
relationship: develops_from PO:0000351 ! guard mother cell
relationship: part_of PO:0002000 ! stomatal complex

Is it good to have only the ID or do you want us to add the term name as 
well. Is there a better way?

Pankaj
