    Study Notes

    Kingdom Plantae Class Notes

    • Plant Reproduction Classifications:

      • Bryophyta (Amphibious Plants, eg. Moss)
      • Gymnosperm (Naked seeds, eg. Pine)
      • Angiosperm (Seeds enclosed, eg. Flowering plants)

    • Plant Divisions:

      • Non-Vascular Plants (Bryophyta):

        • Reproduce with flagellated sperm
        • Limited to moist environments
        • Nutrients transported through diffusion

      • Vascular Plants (Tracheophytes):

        • Have vascular tissue (tubes) for transporting water and nutrients
        • More resistant to drying out
        • Can grow larger and have roots, stems, and leaves

    • Angiosperm Types:

      • Monocots:

        • Flower parts in multiples of three
        • Slender leaves with scattered veins
        • Vascular tissue spread throughout the stem

      • Dicots:

        • Flower parts in multiples of four or five
        • Broad leaves with branched veins
        • Vascular tissue arranged in a ring

    • Plant Tissues:

      • Roots:
        • Absorb nutrients
        • Stabilize the plant
        • Produce hormones
      • Stems:
        • Support and transport
        • Store nutrients
      • Leaves:
        • Collect sunlight for photosynthesis
        • Blade, petiole, epidermis and cuticle
        • Guard cells regulate gas exchange (CO2/O2)

    • Stem Tissues:

      • Dermal: Outer surface
      • Ground: Cells around vascular tissue (starch storage, photosynthesis)
      • Vascular: Transport and support

    • Stomata:

      • Located on the underside of leaves
      • Open/close to regulate gas exchange (CO2/O2)
      • Protected by guard cells

    • Root Types:

      • Taproots: Thick, central root with smaller branches
      • Fibrous roots: Numerous thin roots spreading out

    • Root Structures:

      • Meristems: Actively growing parts
      • Root cap: Protects meristems
      • Epidermis: Forms root hairs for nutrient absorption

    • Plant Hormones:

      • Auxins: Control growth and direction
      • Gibberellins: Seed germination, stem elongation
      • Cytokinins: Cell division
      • Ethylene: Ripening
      • Abscisic Acid: Dormancy

    • Plant Succession:

      • Primary: Starts in bare areas (no soil)
      • Secondary: Follows a disturbance (e.g., fire)

    • Water Movement in Plants:

      • Root pressure: Water moves up stems due to root pressure
      • Capillary action: Water moves up due to properties of water
      • Transpiration: Water is drawn through the plant due to evaporative pull from leaves

    Additional Notes:

    • Cotyledon: Seed leaves, which provide nutrients for the embryo.
    • Embryo: Initial stage of development for multicellular organisms.
    • Perennials/Annuals: Plants living for more than two seasons or a single growing season respectively.
    • Primary root: Originates from the seed.
    • Secondary root: Originates from the primary root.
    • Taproot System: Composed of a prominent main root with smaller lateral roots, commonly found in dicots.
    • Fibrous Root System: Composed of a network of similarly sized thin roots, commonly found in monocots.
