    Study Notes

    Structures in the Epidermis of Leaves

    • Stomata regulate transpiration and gaseous exchange.
    • Guard cells surround each stomatal pore, controlling its opening and closing.
    • Trichomes play a role in reducing water loss by creating a barrier against air movement.

    Outer-Most Covering

    • The epidermis forms the outermost covering of the whole plant body, providing protection.

    Cells Enclosing Stomatal Pore

    • Guard cells typically enclose the stomatal pore in most plants, facilitating gas exchange.

    Function of the Cuticle

    • The cuticle is a waxy layer that reduces water loss and protects the epidermis from pathogens and environmental stress.

    Tissue System for Transport

    • The vascular tissue system is responsible for transporting water, minerals, and organic compounds throughout the plant.

    Function of Subsidiary Cells

    • Subsidiary cells assist in maintaining turgor pressure in guard cells, aiding in the regulation of stomatal openings.

    Cells Preventing Water Loss

    • Guard cells, along with trichomes, help prevent excessive water loss due to transpiration.

    Function of Trichomes

    • Trichomes provide protection, reflect excess sunlight, and reduce water loss by trapping moisture.

    Vascular Arrangement in Dicotyledonous Stems

    • Cambium is present between the phloem and xylem, allowing the formation of secondary tissues and growth.

    Arrangement of Vascular Bundles

    • In some vascular bundles, xylem and phloem are arranged along the same radius, facilitating efficient transport.

    Functions Summary

    • The cuticle minimizes water loss and serves as a protective barrier.
    • Trichomes contribute to plant defense and moisture retention in the shoot system.
