A nice explanation of the Immaculate Conception, from Theology for Beginners
In seeing what the difference is, a good starting point is the simple fact that this Son existed before his mother. So that he is the only Son who was in a position who choose who his mother should be; he could choose therefore what every son would choose if he could, the mother who would suit him best. Further, it goes with the very heart of sonship that a son wants to give his mother gifts; and Christ, being God, could give her all that she would want. To his giving power there was no limit. And what above all she wanted was union with God, the completest union possible to a human being of her will with God's will, grace therefore in her soul.
He was her Son, and he gave it lavishly. She responded todally, so that she was sinless.
