Female and male sex cells, animation

Videonummer 12081363
Female and male sex cells. Labelled animation of human female and male reproductive cells (also called sex cells or gametes). The female sex cell is the ovum, and the male sex cell is the spermatozoon (sperm cell). The animation starts with a view of the ovum, which has a diameter of 0.1 millimetres. The two outer layers are shown: the corona radiata (rounded objects) and the zona pellucida (brown outer ring). Also present is the nucleus (black) and the ovum's cytoplasm (yellow). The animation then shows a single uniflagellar sperm cell in its motile state. It is much smaller, being 0.055 millimetres long. It consists of a tail, the cell's plasma membrane, the midpiece (green and white), the neck, and the head (yellow and pink). Within the head is the nucleus (yellow) and the acrosome (pink). Within the midpiece are mitochondria (white) that provide energy. Both the ovum and sperm cell contain genetic material (deoxyribonucleic acid, DNA). Fertilisation occurs when the genetic material in the sperm's head fuses with the egg's DNA to form a zygote. Unlabelled version: K005/5694. Alternative labelled version: K005/5705.
