  • What is the anatomy of a plant?
    It is its internal structure.
  • What will you learn about in this unit regarding dicotyledonous plants?
    You will learn about the structure and functions of tissues that make up the root and stem.
  • What are the key questions in Unit 1 regarding dicotyledonous plants?
    • Which tissues make up the root and stem?
    • How are tissues arranged in the root and stem?
  • What is the endodermis in dicotyledonous plants?
    It is the tissue that surrounds the central vascular tissue.
  • What is the cortex in dicotyledonous plants?
    It is the tissue between the epidermis and vascular tissue in roots and stems.
  • What is the Casparian strip?
    It is a waxy, waterproof band in the cell walls of the cells of the endodermis.
  • What is the pericycle?
    It is a layer of parenchyma cells that forms lateral roots.
  • What is vascular tissue composed of?
    It is composed of xylem and phloem.
  • What is cambium in dicotyledonous plants?
    It consists of cells that can divide by mitosis to produce more xylem and phloem cells.
  • What are the main components of root structure in dicotyledonous plants?
    • Epidermis: Protects the root from injury and allows water uptake.
    • Cortex: Transports water and stores starch.
    • Endodermis: Channels water into the xylem.
    • Pericycle: Forms lateral roots.
    • Vascular tissue: Contains xylem, phloem, and cambium.
  • What is the function of roots in dicotyledonous plants?
    Roots anchor the plant in the soil and absorb water and dissolved minerals.
  • What should you be able to do regarding the plant diagram in this unit?
    Be able to draw it!
