Equal cells

Though the egg stays in one place, and doesn't have a little wavy tail that enables it to travel, you can say the main function of the egg is to "receive" the sperm cell in an almost seemingly passive way , the egg realistically is a very powerful, sacred cell, equally as important and constructive as the sperm. The way I look at it is that they are simply a puzzle, one wouldn't be able to fulfill the ultimate destiny properly without the other, it is a two way road.
