    Study Notes

    Science Module 5: Modes of Reproduction in Flowering and Non-Flowering Plants

    • This module covers the different methods of reproduction in plants
    • It differentiates between sexual and asexual reproduction in plants
    • Reproduction is the production of new individuals or offspring from their parents
    • Sexual reproduction involves the production of seeds
    • Asexual reproduction does not involve the production of seeds
    • The module includes two key lessons covering sexual and asexual reproduction in plants

    Sexual Reproduction in Plants (Lesson 1)

    • Flowers are essential reproductive structures in flowering plants
    • Pollination is essential, involves the transfer of pollen from anther to stigma
    • Two types of pollination
    • Self-pollination: Pollen is transferred within the same flower or to another flower on the same plant
    • Cross-pollination: Pollen is transferred to another flower on a different plant of the same species
    • Pollen grains develop into seeds, leading to new plant growth

    Asexual Reproduction in Plants (Lesson 2)

    • Plants can reproduce asexually through various methods, leading to offspring genetically identical to the parent plant

    • Asexual methods includes natural vegetative propagation (runners, bulbs, tubers, rhizomes, plantlets) and artificial vegetative propagation (cuttings, grafting, marcotting, budding, layering)

    • Natural methods:

    • Runners: Horizontal stems that grow along the ground (example: strawberries)

    • Bulbs: Modified stems with fleshy leaves (example: onions)

    • Tubers: Swollen underground stems (example: potatoes)

    • Rhizomes: Underground stems (example: ginger, bananas).

    • Plantlets: New plants growing from plant leaves. (example: begonias).

    • Artificial methods:

    • Cuttings: A piece of stem, leaf or root developed into a new plant (example: mangoes, roses)

    • Grafting: The cutting (scion) of a plant placed on a rootstock (example: mangoes, citrus)

    • Marcotting: Stems placed on the ground to create roots and new plants (example: orchids)

    • Layering: Part of a stem (or stem branch) is bent over and covered in soil to encourage roots (example: garden plants)

    • Budding: Insertion of buds onto a stem (example: citrus)

    • Many plants can reproduce both sexually and asexually.
