Trends of 'sperm'

Description:Published by Houghton Mifflin Company. Sperm cells are haploid they have half the number of chromosomes as the other cells in the organism's body. Sperm often have at least one flagellum. During fertilization, the nucleus of a sperm fuses with the nucleus of the much larger egg cell the female reproductive cell to form a new organism. In male animals, sperm are normally produced by the testes in extremely large numbers in order to increase the chances of fertilizing an egg. Motile sperm cells produced by some multicellular protist groups such as the algae , the bryophyte plants, and the seedless vascular plants, require water to swim to the egg cell.
