Cross-pollination is the transfer of pollen from the anthers of a flower to the stigma of a flower on another planet of the same species. Semen is pushed out of the male's body through his urethra — this process is called ejaculation. Flowers and pollen grains are modified to facilitate the process of cross-pollination. In the human reproductive process, two kinds of sex cells, or gametes pronounced: GAH-meetz , are involved. The figure below shows the structures of the placenta.

Then, after the videos, these can be re-visited these to fully understand the cause and effect relationship seen in the videos. Anthers produce these numerous yellowish pollen grains, which contain male gametes. One or more such buds may be produced from a single parent body.

It takes only one sperm to fertilize the egg. When offspring is produced by a single parent with or without involvement of gamete formation, the type of reproduction is sexual. The bud may be unicellular as in some protozoans suctoria or multicellular as in certain lower metazoans like, Sycon sponge , Hydra Goelenterate , Planaria flatworm , Syllis annelid etc. Once fertilized, the egg begins to develop into an embryo in much the same way that an animal embryo develops. Some boys are circumcised, which means that a doctor or clergy member cuts away the foreskin.
