Scanning Electron Micrograph (SEM) showing fertilization; note polar body. Before ovulation the egg cell undergoes meiotic division giving rise to two cells: a secondary oocyte and a polar body. The polar body degenerates and has no function, while the much larger egg develops in preparation for fertilization. Magnification unknown.
