                     Vocabulary A-Z
                     Let us learn some vocabulary



         Reproduction
         the process by which new organisms are produced.


                                                           Fertilization
                                                           a reproductive process in which a sperm joins with
                                                           an egg.
                           Asexual









                            Sexual                                            Fertilization




         Gamete
          human reproductive cell.                         Zygote
                                                           the cell that forms when a sperm cell fertilizes an
                                                           egg cell.
