Detailed explanation-1: -The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth).

Detailed explanation-2: -tissue formation Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium. They produce secondary tissues from a ring of vascular cambium in stems and roots.

Detailed explanation-3: -Lateral meristems occur at the cambium and are responsible for secondary growth (i.e. plant widening / thickening) Apical meristems give rise to new leaves and flowers, while lateral meristems are responsible for the production of bark.

Detailed explanation-4: -Lateral meristems are the meristems that are present at the longitudinal axis region of the roots and shoots of the plants. The function of lateral meristem is to increase the thickness of the plants.

Detailed explanation-5: -There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides).
