    Study Notes

    Reproduction in Plants

    • Plants reproduce to create new individuals.
    • This process is different for different plants.
    • Reproduction can be asexual or sexual.

    Asexual Reproduction

    • Asexual reproduction does not involve the joining of male and female gametes.
    • New plants are created from parts of the parent plant.
    • This way creates new plants identical to the original plant.
    • Methods include:
      • Vegetative Propagation. New plants grow from roots, stems, leaves, or buds.
        • Examples include stem cuttings, root cuttings.
      • Spore Formation. Spores are tiny reproductive cells that develop into new plants (e.g., ferns ,mosses, fungi).
      • Budding. New individuals develop from the parent organism (e.g., yeast).

    Sexual Reproduction

    • Plants use sexual reproduction to make new plants that are genetically distinct from the parent plant. Male and female gametes combine to form a zygote (fertilized egg).
    • This creates a new plant with a unique combination of characteristics from both parents.
    • Involves flowers. Male part is stamen and female part is pistil.
    • Flowers have male parts to produce pollen(pollen grains).
    • Flowers have female parts to accept the pollen (stigma, style, ovary).
    • Pollen reaches the pistil through pollination.
    • Pollination can be done by wind, water, or animals that carry pollen to different flowers or parts of the same flower.
    • Fertilization occurs when the pollen combines with the egg in the ovary to form a zygote.
    • The zygote develops into the embryo of a seed.
    • The ovary develops into a fruit which protects the seed and helps disperse it.
    • Various methods for seed dispersal exist like wind, water, animals.

    Modes of Reproduction in Plants

    • Two main types of reproduction exist, asexual and sexual reproduction.
    • Asexual reproduction produces offspring that are genetically identical to the parent. It's faster and easier, useful for creating many offspring.
    • Sexual reproduction produces offspring with unique combinations of characteristics. It ensures genetic diversity, which is important in a changing environment.
