    Study Notes

    Plant Habit

    • Plant habit refers to the general growth form of a plant
    • Herbaceous (herb) plants have no woody tissue
    • Examples of herbaceous plants include beans and irises

    Leaf Arrangement

    • Opposite clusters of leaves can give the appearance of a whorl or verticel due to overcrowding
    • Verticels are arranged in a racemose manner

    Epidermal Cells

    • Cutine and other waxy polymers are deposited on the free surface of epidermal cells, forming a structure called cuticle

    Cell Wall Composition

    • Pectins have more links with cellulose than hemicellulose with cellulose
    • Pectins help to hydrate the primary cell wall

    Tissue Development

    • Leaf primordia arise from the eumeristem
    • Procambium and cortical ground tissue also arise from this region
