  • Sexual Reproduction
    • Gametes
      • Specialised cells that are  produced by    Males and       Females
      • Animals:    Sperm and Egg cells
        • Sperms are specialised for movement towards female Gamete
        • Egg celss are specialised for cell division by having large food store
      • Plants:       Pollen and Egg grain
      • Fuse together at Fertilisation
      • Contain genetic information in the form of Genes
    • Requires 2 organisms of the same species
    • Fertilisation
      • Fusion of Gametes in Animals
        • Produces a cell which contains genetic information from both parents
          • Cell divides rapidly to produce more cells with each having exactly the same genetic information
      • Fusion of Gametes in Plants
        • Produces a cell which contains genetic information from both parents
          • This cell is inside a seed which helps it to divide to form an embryo, all the cells of which have the same genetic information.
    • Artificial Pollination
      • When a breeder's motive is to produce a new variety of a plant. They select their desired type of plant, they then hand-pollinate individual plants using the selected plants pollen, then placing transparent plastic bags over the female reproductive organs..
