And we'll discuss what these other cells are in just a moment. So we have the primary follicle that contains the diploid primary Oocide. And the primary follicle during the process, during the menstrual cycle will eventually develop into the secondary follicle. And the secondary follicle is much larger because it contains much more fluid, it contains many more cells and it also contains the secondary Oocide. So the primary follicle contains the primary Oocide which is a diploid cell. And then we have the secondary follicle that contains the secondary Oocide which is a haploid cell.
