Detailed explanation-1: -Tissues made up of actively dividing cells are called meristematic tissues or meristems. Meristematic tissues are responsible for plant growth. They are present at the tips of roots, stem and branches. The cells present in these tissues constantly divide to produce new cells.

Detailed explanation-2: -A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells constantly divide to give rise to various organs of the plant and keep the plant growing.

Detailed explanation-3: -Meristems are tissues in a plant consisting of undifferentiated cells capable of indeterminate growth. They are analagous to totipotent stem cells in animals, except that they have specific regions of growth and development.

Detailed explanation-4: -Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.

Detailed explanation-5: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).
