  • A leaf is a plant organ and is made up of a collection of tissues in a regular organisation.

    The major tissue systems present are: :

    1. The epidermis that covers the upper and

    lower surfaces

    2. The mesophyll inside the leaf that is rich

    in chloroplasts (also called chlorenchyma)

    3. The arrangement of veins (the vascular

    tissue)

    These three tissue systems typically form a

    regular organisation at the cellular scale
