It's sperm to bind to the plasma membrane, the acrosome is gone, I'll erase and here. And the zona pellucida is a thick layer of glycoproteins that sit on the outside of the egg. And they wait and their entire job is to wait egg video a sperm to bind.
And the sperm cell has a whole bunch packed right into the base of the flagellum here. And potentially, some of these mitochondria can get sucked in during that genetic transfer process as well. Egg, sperm, and fertilization.

Egg, sperm, and fertilization
We can see that it's a very mobile structure evolved basically to get genetic material from the male to the female egg cell. You sperm and egg video see, just like a torpedo, it has a pointed head which allows it to travel in the forward direction. Well, the egg cell has mitochondria too. So keep those mitochondria in mind, we'll talk about them a little bit later in the next section. And they wait and their entire job is to wait for a sperm to bind.
