Reproduction



         This is the process by which living things multiply and in-

         crease in number (become many) i.e. give rise to new off-

         springs (young ones) to continue a generation of the species.

































         There are two types of reproduction

         1. Asexual reproduction


         2. Sexual reproduction




         1. Asexual reproduction


         This is the type of reproduction where no reproductive cells

         (gametes) are used to produce young ones.



         Examples of a sexual reproduction


         Vegetation propagation in plants e.g. budding, grafting, layer-

         ing,  marcotting,  stem  cutting,  bulbs  crown,  slips,  leaves,  and

         root  cutting,  cell  division,  binary  fission  in  single  celled  ani-

         mals e.g. Amoeba, bacteria, paramecium.
