    Study Notes

    Meristematic Tissues

    • Meristematic tissues are the only type of tissues that actively divide throughout their life and remain young forever.

    Cambium

    • The cambium is a type of meristematic tissue located between the xylem and phloem in the stem and root of plants.
    • The function of the cambium is to produce new xylem and phloem cells, allowing the plant to grow in diameter.

    Plant Responses to Water Stress

    • During water stress, special cells in plants called pulvinar cells make the leaves curl up.

    Photosynthesis

    • The product of photosynthesis is stored in the form of starch in the chloroplasts of plant cells.

    Plant Anatomy

    • Debarking a tree removes the bark, which is the outermost layer of the plant, protecting the inner tissues.
