Answer:
Meristem, region of cells capable of division and growth in plants. Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses). Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness. Meristems form anew from other cells in injured tissues and are responsible for wound healing. Unlike most animals, plants continue to grow throughout their entire life span because of the unlimited division of meristematic regions.

Meristematic cells are typically small and nearly spherical. They have a dense cytoplasm and relatively few small vacuoles (watery saclike enclosures). Some of these cells, known as initials, maintain the meristem as a continuing source of new cells and may undergo mitosis (cell division) many times before differentiating into the specific cells required for that region of the plant body. The cells that emanate from the apical meristem are arranged in lineages of partially differentiated tissues known as primary meristems. 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).

The shoot apical meristem of Hypericum uralum (left) appears at the topmost aspect of the stem. Immediately behind the apical meristem are three regions of primary meristematic tissues. The root apical meristem (right) appears immediately behind the protective root cap. Three primary meristems are clearly visible just behind the apical meristem.
