Description
Fertilization. Colored Scanning Electron Micrograph (SEM) of a sperm on the surface of a human egg (ovum) during fertilization. The egg has a furry surface (brown). The sperm attached to it is a hair-like structure (blue); it has a head (upper center) and a long tail. Here, it is penetrating this thick surface of the egg that attracts the sperm and enables it to attach. The human female usually produces a single large egg, and only one of the millions of male sperm released may penetrate the egg to fuse with the egg nucleus. Once fertilized, the egg begins its process of growth into a human embryo. Magnification x4,600 at 6x9cm size.
