  • Reproductive Strategies of Plants.
    • Sexual Reproduction
      • Usually involves two parents.
        • Less rapid than asexual and produces  offspring that are genetically different.
          • Diploid body cells produce haploid sex cells or Gametes
            • The fusion of haploid gametes is always involved.
      • Advantages
        • There is an increase ion genetic variety
          • This enables species to adapt to environmental change.
        • It allows the development of a resistant stage in the life cycle.
          • Enables the species to withstand adverse conditions
        • The formation of spores, seeds, and larvae enables the dispersal of offspring
          • This reduces intra specific competition.
            • Enables genetic variety to develop as required.
              • Untitled
      • Disadvantages
        • A much slower process than asexual reproduction.
    • A-Sexual Reproduction
      • Involves only one parent
        • The rapid production of  large numbers of offspring.
          • Have a genetically identical composition
            • Called Clones.
      • Examples of A-Sexual Reproduction
        • Binary Fission
        • Budding
        • Bulbs e.g. Daffodil.
        • Runners e.g. Strawberries
        • Tubers e.g. Potato
