Neck Canal Cells are found in archegonium (female reproductive system) Of Bryophytes and Pteridophytes. (6-10 in Bryophytes and ! in Pteridophytes)
The structure of The archegonium is flask shaped with a  narrow neck. Inside this neck is present the neck canal cell.
 
Before fertilization, these cells break down (dehiscence)  and secrete chemicals which are used to attact the male gametes. (Venter canal cells are also present just above the egg and the neck cells are present above the venter canal cells, and neck canal cells and venter canal cells degenarate together and secrete the chemicals )
