[Spider-Man] Why did Peter Parker not gain web powers?

In the comics, Peter does not gain web powers from the spider bite, he creates the webbing himself. In the Raimi trilogy, he gets webbing powers. Why wouldn't he get webbing powers in the first place? He gets all other powers of a spider, and the webbing is like the most important power.

Peter's powers are, believe it or not, magical in nature, and not purely biological. The spider bite didn't give him the necessary organs to produce the webbing, but imparted with him the knowledge to make the webs.
