6. ANATOMY OF FLOWERING PLANTS

The anatomy of flowering plants is structured into various tissues that organize into three main systems: epidermal, ground, and vascular. These systems are crucial for supporting plant functions such as water and nutrient transport, and photosynthesis. Dicotyledonous and monocotyledonous plants display distinct internal anatomical characteristics influenced by their structure and growth processes.

  • 6.1

    The Tissue System

    The tissue system in flowering plants consists of the epidermal, ground, and vascular tissue systems, each serving distinct structural and functional roles.

    Learning Practice

  • 6.1.1

    Epidermal Tissue System

    The epidermal tissue system is the outermost layer of the plant body, consisting of epidermal cells, stomata, and appendages that protect the plant and regulate water loss.

    Learning Practice

  • 6.1.2

    The Ground Tissue System

    The ground tissue system comprises simple tissues like parenchyma, collenchyma, and sclerenchyma, which fulfill various functions in the plant body.

    Learning Practice

  • 6.1.3

    The Vascular Tissue System

    The vascular tissue system consists of complex tissues, including xylem and phloem, which are essential for transporting water and nutrients in plants.

    Anatomy Of Dicotyledonous And Monocotyledonous Plants

    This section outlines the anatomical differences between dicotyledonous and monocotyledonous plants, detailing their root, stem, and leaf structures.

    Learning Practice

  • 6.2.1

    Dicotyledonous Root

    This section details the anatomy of dicotyledonous roots, highlighting the organization and function of various tissues and structures.

    Learning Practice

  • 6.2.2

    Monocotyledonous Root

    The monocotyledonous root has a specific anatomical structure, typically featuring multiple vascular bundles and a well-developed pith.

    Learning Practice

  • 6.2.3

    Dicotyledonous Stem

    The dicotyledonous stem exhibits a complex internal structure, characterized by an epidermis, multilayered cortex, and a distinctive arrangement of vascular bundles.

    Learning Practice

  • 6.2.4

    Monocotyledonous Stem

    The monocotyledonous stem features a sclerenchymatous hypodermis, scattered vascular bundles, and a large parenchymatous ground tissue.

    Learning Practice

  • 6.2.5

    Dorsiventral (Dicotyledonous) Leaf

    The dorsiventral leaf structure consists of an epidermis, mesophyll, and vascular system, with distinct features aiding in photosynthesis.

    Learning Practice

  • 6.2.6

    Isobilateral (Monocotyledonous) Leaf

    The isobilateral leaf anatomy features stomata on both surfaces and non-differentiated mesophyll.

    Learning Practice
