a toilet paper or absorbent paper is placed, the paper is moistened and the seeds are placed on the paper, then covered with another moistened paper, this is done with the intention of stimulating the germination of the seeds maintaining moisture, then it is periodically reviewed to determine according to the amount of germinated seeds if these are viable for sowing.

I remember doing that in elementary school. Didn't remember why that was done. Never really thought about it. It all makes sense now.
