    Study Notes

    1. Plants have three basic organs: roots, stems, and leaves, composed of three kinds of tissues.
    2. Learning outcome: identify and describe plant organs, tissues, and cells for subsequent lessons.
    3. Roots anchor plants, absorb water and minerals, and store carbohydrates.
    4. Modified roots serve additional functions such as structural support, storage, and resource acquisition.
    5. Stems support leaves and reproductive shoots and distribute water, minerals, and photosynthates throughout the plant.
    6. Modified stems store carbohydrates and propagate plants asexually.
    7. Leaves are the main photosynthetic organ and have a diversity of shapes.
    8. Modified leaves serve various functions such as climbing, defense, storage, and reproduction.
    9. There are three tissue systems in plants: dermal, vascular, and ground.
    10. Dermal tissue functions in defense and water loss prevention through the epidermis or periderm.
    11. Vascular tissue transports water and minerals through xylem and organic nutrients through phloem.
