    Study Notes

    Meristematic Tissue

    • Regions in plants responsible for producing new cells.
    • Called meristems - from the Greek word "merizein" meaning "to divide."
    • Responsible for growth and cell differentiation.
    • Cell differentiation is the biochemical and physical change in cells leading to specialization.
    • Meristems produce new cells and tissues.

    Permanent Tissue

    • Tissues that are already specialized and no longer divide.
    • Composed of living cells or dead cells.
    • Positioned in a plant as simple or complex tissues.
