Sperm and Eggs Cells

The video explains the role of gametes, which are reproductive cells like egg and sperm cells, in human reproduction. Gametes are haploid, containing 23 chromosomes, unlike other body cells that are diploid with 46 chromosomes. The video highlights the differences between egg and sperm cells, such as size and function. Egg cells are larger and stationary, while sperm cells are smaller and motile. Fertilization occurs when a sperm cell fuses with an egg cell, combining their chromosomes to form a diploid zygote. The structure of sperm cells, including their energy-producing head and motile tail, is also discussed.
