    Study Notes

    Classification of Living Organisms

    • The highest category in the traditional Linnaean system of classification is the kingdom, which distinguishes organisms based on cellular organization and methods of nutrition.
    • Plants and animals are macroscopic and easy to differentiate.

    Reproduction in Organisms

    • Simple organisms reproduce through asexual reproduction, producing offspring with identical genes, referred to as "clones".
    • Sexual reproduction in animals involves the production of new living organisms by combining two gametes from different organisms.

    Plant Reproduction

    • Plants can reproduce through either sexual or asexual reproduction.
    • Flowering plants reproduce sexually through pollination, which involves the transfer of pollen from one flower to another.

    Pollination Process

    • Pollination can occur through self-pollination or cross-pollination.
    • The flowers contain male sex organs called stamens and female sex organs called pistils.
    • The pedicel is the stalk that attaches an individual flower to the main axis of the inflorescence.
    • The peduncle is the stalk that joins the base of an inflorescence to the main stem.
    • The petiole is the stalk that attaches a leaf blade to the main stem.
    • Sepals are the outer parts of a flower that enclose and protect the unopened flower bud, collectively referred to as the calyx.
    • Petals are the second whorl of the flower, sterile floral parts that attract insects for pollination and protect the reproductive organs.

    Plant Reproductive Organs

    • Stamens are the male reproductive parts of the flower, consisting of the anthers and filaments.
    • Anthers produce and hold pollen, while filaments support the anthers and bring them into contact with pollinators.
    • The pistil is the female reproductive part of a flower, consisting of the ovary, style, and stigma.

    Asexual Reproduction in Plants

    • Asexual reproduction in plants includes vegetative propagation and fragmentation.
    • Vegetative propagation involves offspring growing from a part of the parent plant, such as true bulbs, corms, tubers, rhizomes, and stolons.
    • Fragmentation involves new plants growing from small parts of the parent plant that fall to the ground.
