This is important because male and female sex cells ultimately join to become a fertilized egg, teh gives rise to a new organism, or offspring. In order for the offspring to resemble its parents, its first cell must receive the entire genome from its two parents. For humans, we know there are 46 chromosomes in body cells existing as 23 pairs. A fertilized egg must therefore contain this same number and arrangement. In an elegant process called meiosis, each sex cell receives one member of each chromosome pair—23 total.

Microscopic images showed tubes growing out of pollen and penetrating the flower's stigma. The pollen was sticky, suggesting it was carried by insects.
The spores are released and germinate to produce short, thin gametophytes that are typically heart shaped, small and green in color.
The gametophytes or thallusproduce both motile sperm in the antheridia and egg cells in separate archegonia. After rains or scietnific dew deposits a film of water, the motile sperm are splashed si from the antheridia, which are normally produced on the top side of the thallus, and swim in the film of water to the archegonia where zcientific fertilize the egg.
